who is the father of kinematics ?
explain +)
Answer:
FRANZ REULEAUX
Late 19th century kinematics and the theory of machines as seen through the contributions of the German engineering scientist, Franz Reuleaux (1829-1905), often called the "father of kinematics". Extremely famous in his time and one of the first honorary members of ASME, Reuleaux was largely forgotten in much of modern mechanics literature in English until the recent rediscovery of some of his work. In addition to his contributions to kinematics, we review Reuleaux's ideas about design synthesis, optimization and aesthetics in design, engineering education as well as his early contributions to biomechanics. A unique aspect of this review has been the use of Reuleaux's kinematic models at Cornell University and in the Deutsches Museum as a tool to rediscover lost engineering and kinematic knowledge of 19th century history of machine.

A ball traveling at 15 m/s hits a bat with a force of 200N. How much force does the bat (moving at 20m/s)
hit the ball with?
O 200
O 15
O 20
O 20
Answer:
200 N
Explanation:
Given that,
A ball traveling at 15 m/s hits a bat with a force of 200 N.
We need to find the force that the bat moving at 20 m/s hit the ball with.
We know that, this probelm is based on Newton's third law of motion. The force that the ball exerting on bat should be equal to the force that the bat exerting in the ball but in opposite direction.
It would mean that the ball hits the ball with a force of 200 N. Hence, the correct option is (a).
A car accelerates from rest. It reaches a velocity of 25m/s in 10 seconds. What was the cars acceleration?
Answer:
We are Given:
initial velocity (u) = 0m/s
final velocity (v) = 25 m/s
time (t) = 10 seconds
acceleration (a) = a m/s/s
From the first equation of motion, we know that:
v = u + at
solving for a, we get:
a = (v-u) / t
now, plugging the given values in this equation
a = (25 - 0) / 10
a = 25 / 10
a = 2.5 m/s/s
Therefore, the acceleration of the car is 2.5 m/s/s

Rihanna can go from 0-60 miles per hour in 3.5 seconds. Calculate the acceleration.
Please show ALL work and CIRCLE your answer.
Answer:
7.66 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 mph
Final velocity (v) = 60 mph
Time (t) = 3.5 s
Acceleration (a) =.?
Next, we shall convert mile per hour (mph) to metre per second (m/s). This can be obtained as follow:
Recall:
1 mph = 0.447 m/s
Initial velocity (u) = 0 mph
Initial velocity (u) = 0 × 0.447 = 0 m/s
Final velocity (v) = 60 mph
Final velocity (v) = 60 × 0.447 = 26.82 m/s.
Finally, we shall determine the acceleration of Rihanna as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 26.82 m/s.
Time (t) = 3.5 s
Acceleration (a) =.?
a = (v – u) /t
a = (26.82 – 0) / 3.5
a = 26.82 / 3.5
a = 7.66 m/s²
Thus, the acceleration of Rihanna is 7.66 m/s²

In which position is it most likely that the spring has lost its elastic potential energy?
A.W
B.X
C.Y
D.Z
Answer:
w
Explanation:
its not being streched lol hope dis help
Option A is correct. At position W the spring will lose its elastic potential energy. When spring is extended or shortened, work is done. In the spring, elastic potential energy is stored.
What is the elastic potential energy of spring?When a spring is stretched or compressed, work is done. In the spring, elastic potential energy is stored.
The work done is equal to the elastic potential energy stored, assuming no inelastic deformation has occurred.
The potential energy of the spring is equal to the work done on the spring;
Potential energy = Work done
The mechanical potential energy contained in the structure of a material or physical system as it is forced to elastic deformation by work done on it is referred to as elastic energy.
When things are impermanently crushed, extended, or distorted in any way, elastic energy is released.
The mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work done on it is referred to as elastic energy.
At position W, the spring has zero deformation. So there should be no stretching causes the potential energy of the system is zero.
Hence option A is correct. At position W the spring will lose its elastic potential energy.

A bird uses 10 N of force to pull a worm out of the ground a distance of 3 inches. How much work did the bird do?
Answer:
The work done by the bird is 0.762 J
Explanation:
Given;
force applied by the bird, f = 10 N
distance the bird moved the worm, d = 3 inches = 0.0762 m
The work done by the bird is given by;
W = F x d
where;
W is the work done by the bird
d is the distance the bird moved the load
Substitute the given values and estimate the work done by the bird;
W = 10 x 0.0762
W = 0.762 J
Therefore, the work done by the bird is 0.762 J
A projectile in flight explodes into several fragments. The total momentum of the fragments immediately after this explosion: ___________
a. is the same as the momentum of the projectile immediately before the explosion
b. has been changed into kinetic energy of the fragments
c. is less than the momentum of the projectile immediately before the explosion
d. is more than the momentum of the projectile immediately before the explosion
e. has been changed into radiant energy
Answer:
answer is a.
Explanation:
Newton's first law: inertia
If you still can't get it, look at the book.
the conservation of momentum:
the total momentum of a system is conserved, provided that there is no external net force acting on the system.
The total momentum of a system is conserved. Therefore, the total initial momentum of a body after collision is equal to the total final momentum. Thus, option a is correct.
What is momentum ?Momentum of an object is the ability of an object to bring the force applied to make a maximum displacement. It is the product of its mass and velocity. Momentum is a vector quantity. It have both magnitude and direction.
The momentum in a collision is conserved. Thus total initial momentum is equal to the final momentum. Let m be the colliding mass and the u and v be the initial and final velocity.
Then, mu = m v after collision.
The initial momentum of the flight will be equal to the total momentum of the fragments immediately after the explosion. This is called conservation of momentum.

The height of the bullet as it travels is 72727.27 ft.
What is height?Height is the vertical distance between two points. The unit of height is meter (m).
To calculate the height the bullet will go, we use the formula below
Formula:
v² = u²+2gH.............. Equation 1Where:
v = Final velocity of the bulletu = initial velocity of the bulletg = acceleration due to gravityH = Height the bullet will go.Make H the subject of the equation
H = (v²-u²)/2g................ Equation 2From the question,
Given:
u = 1200 ft/sv = 0 m/s (at maximum height)g = -9.8 m/s² (against gravitational force)Substitute these values into equation 2
H = (0²-1200²)/2×(-9.8)H = -1440000/-19.8H = 72727.27 ft.Hence, The height of the bullet as it travels is 72727.27 ft.

what is the kinetic energy of the boulder when it lands?
what is the potential energy on the cliff?
How high is the cliff??
Given:-
Mass of boulder = 10kg
Final Velocity = 15m/s
Acceleration due to gravity = +10m/s
To Find:-
The kinetic energy of the boulder as it lands
The potential energy of the boulder when it was at the top of the cliff
The height of the cliff
Formulae used:-
Kinetic energy = mv²/2
Potential energy = mgh
Now,
We will first find the Kinetic enrgy,
→ K. E = ½mv²
→ K. E = ½ × 10 × (15)²
→ K. E = 5 × 225
→ K. E =1125J
But we know that when the body starts moving the Potential enrgy of the body starts Converting into Kinetic enrgy. Before reaching to the last spot it has equal kinetic energy and Potential energy.
Therefore,
→ mgh = 1125J
The Potential enrgy of the boulder when it was on top is 1125J
Now,
→ mgh = 1125J
→ 10 × 10 × h = 1125J
→ 100h = 1125J
→ h = 1125/100
→ h = 11.25m
Hence, The Height of the Cliff is 11.25m
