What is the velocity of a 24 kg object with 108 kg m/s of momentum?
A) 3 m/s
B) 4.5 m/s
C) 6 m/s
D) 84 m/s
Answer:
The velocity of the object is 4.5 m/s
Explanation:
Momentum is equal to mass times velocity. We can rearrange that relationship to say that velocity is equal to momentum divided by mass. With that we can say:
v = 108 kg m/s / 24kg
v = (108 / 24) m/s
v = 4.5 m/s

Calculating net force
Answer:
0N.
Explanation:
Net force is the sum total of forces acting on an object.
The Fn which is the net force is
450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)
= 450-250+(-600)+ 600+0+250-450
= 0N
The net force is 0

If a ball that is 10 meters above the ground is thrown horizontally at 5.51 meters per second. a. how long will it take for the ball to hit the ground? b. how far will the ball travel in the horizontal direction before it hits the ground?
Answer:
a. t = 1.43 s
b. d = 7.88 m
Explanation:
a. The time of flight can be found using the following equation:
[tex] y_{f} = y_{0} + v_{0_{y}}t - \frac{1}{2}gt^{2} [/tex]
Where:
[tex]y_{f}[/tex]: is the final height = -10 m
[tex]y_{0}[/tex]: is the initial height = 0
[tex]v_{0_{y}}[/tex]: is the initial speed in the vertical direction = 0
g: is the acceleration due to gravity = 9.81 m/s²
By solving the above equation for "t" we have:
[tex] t = \sqrt{\frac{2y_{f}}{g}} = \sqrt{\frac{2*10 m}{9.81 m/s^{2}}} = 1.43 s [/tex]
Hence, the ball will hit the ground in 1.43 s.
b. The distance in the horizontal direction can be found as follows:
[tex] x_{f} = x_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]
Where:
x₀: is the initial position in the horizontal direction = 0
a: is the acceleration in the horizontal direction = 0 (it is moving at constant speed)
[tex] x_{f} = 5.51 m/s*1.43 s = 7.88 m [/tex]
Therefore, the ball will travel 7.88 m before it hits the ground.

How do plants obtain the carbon dioxide required for photosynthesis?
Answer:
Explanation:
Carbon dioxide in photosynthesis Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata . (singular: stoma. plural: stomata) The lower part of the leaf has loose-fitting cells to allow carbon dioxide to reach the other cells in the leaf.
Answer:
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.

Why is ultraviolet radiation considered more dangerous to humans than infrared radiation?
ANSWER:Ultraviolet radiation has a shorter wavelength than infrared radiation, and thus, the waves have higher energy. This allows them to penetrate the first layers of skin on humans and can mutate the DNA in the cells of the skin. This can result in cancer because of the mutations caused by the ultraviolet radiation.
What happens as a bungee jumper gets closer to Earth's surface?
A. Gravity decreases
B. His mass increases
C. Air resistance decreases
D. His velocity increases
Answer:
Velocity increases
Explanation:
Gravity is constant, except when discussing "apparent weight"
Mass is constant here
Air resistance would actually increase
Velocity DOES increase, because Earth is pulling the jumper downwards with an unbalanced force. The unbalanced force creates acceleration (-9.81 m/s^2), which means his velocity is increasing constantly.

GPE = m*g*h
Answer:
GPEb=67.86% of initial GPE at point a
Explanation:
It depends on how massive the ball is, but I can still give an answer comparing original GPE at point A to new GPE at B
GPEa=m*9.8*140
GPEa=1372(m)
GPEb=m*9.8*95
GPEb=931(m)
GPEb=0.6786*GPEa
a force of 25N acts on an object. The work done by the force is 400J. How far dose the object move in the direction of the force?
A. 6.3cm
B. 16cm
C. 16m
D. 10km
The distance moved by the object in the direction of the force is equal to 16 m. Therefore, option (B) is correct.
What is the work?Work can be demonstrated as the energy employed when a force is exerted to move an object through a specific distance. The work done depends upon both the exerted force on the object and the displacement.
The action of the force when the object is moving in a straight line in the direction of the exerted force over a distance 'd'.
W= F ×d
Where 'd' is the displacement, 'F' is the applied force and W is the work done.
Given, the work done by the applied force, W = 400 J
The force applied on the object, F = 25 N
The distance moved by the object, d = W/F
d = 400/25
d = 16 m
Therefore, the object moves a distance of 16 m in the direction of the force.
