The object is traveling at 10 m/s.

Momentum is defined as the product of an object's mass and velocity. The formula for momentum is:

p=mv

where,

p = momentum

m = mass

v =  velocity

We can use this formula to find the velocity of an object given its momentum and mass. To solve for velocity, we can divide both sides of the equation by mass:

velocity = momentum/mass

In this case, the object has a mass of 40 kg and a momentum of 400 Kgm/s, so we can plug in these values to find the velocity:

velocity = 400 Kgm/s / 40 kg = 10 m/s

Therefore, the object is traveling at 10 m/s.

Impulse is important because it is the force that changes an object's momentum.

Momentum is a physical concept that describes the movement of an object due to the product of its mass and velocity. Momentum is a vector quantity, meaning it has both a magnitude and a direction. In classical mechanics, momentum is conserved, meaning that the total momentum of a system remains constant over time.

In the examples given, impulse is what allows the elevator to be hoisted up, the nylon ropes to hold a climber's weight, the runner to move around the track, and the plane to take off from the runway. Without impulse, none of these activities would be possible.

Answer:

  focal length = 30 cm

Explanation:

You want the focal length of a convex mirror when moving the mirror an additional 15 cm away from the object causes its image size to decrease from 1/2 to 2/5 the size of the object.

The relation between focal length (f), object distance (do) and image distance (di) is ...

  1/f = 1/do +1/di

The ratio of heights is the same as the ratio of distances:

  hi/ho =di/do

If we let do represent the original object distance, then (1/2)do = di, the original image distance. This gives one equation we need:

  1/f = 1/do +1/(1/2do) = 3/do

Moving the mirror increases the object distance to (do+15). Now, the equation becomes ...

  1/f = 1/(do+15) +1/(2/5(do+15)) = 7/(2(do+15))

Substituting for 1/f, we have ...

  3/do = 7/(2(do +15))

  6(do +15) = 7do . . . . . . . . . cross multiply

  90 = do . . . . . . . . . . . . subtract 6·do

Then the focal length is ...

  1/f = 3/do

  f = do/3 = 90/3 = 30

The focal length of the mirror is 30 cm.

A uniformly accelerated straight motion is a motion of an object moving with acceleration or deceleration in a straight line.

The equations apply in vertical dimension are

v₁ = v₀ + gt

v₁² = v₀² + 2gh

h = v₀t + ½ gt²

Where

A penny is dropped off the top of the Statue of Liberty, 93 m tall.

Find the speed of the penny after 2.5 second! (assuming no air resistance)

A dropping off penny has an initial speed of 0.

v₁ = 0

We used g = 10 m/s.

So, the speed at time t = 2.5 s would be

v₁ = v₀ + gt

v₁ = 0 + 10(2.5)

v₁ = 25 m/s

The minimum value of the coefficient of static friction is 1.33.

To calculate the minimum value of the coefficient of static friction, we need to determine the force of static friction acting on the block. The force of static friction is equal to the force of gravity acting on the block (mg) multiplied by the coefficient of static friction (µs

m = 14.26kg

θ = 41°

g = 9.8 m/s²

The force of gravity acting on the block is given by the formula:

Fg = mg

where,

m =  (mass of the block)

g =  (acceleration due to gravity)

Fg = 14.26kg *9.8 m/s²

Fg = 139.75 N

The force of static friction can be found using the formula:

Fstatic = µs * N

where,

µs = coefficient of static friction (unknown)

N = Normal force acting on the block

The normal force acting on the block is equal to the force of gravity acting on the block perpendicular to the ramp.

N = mg * cos(θ)

where,

θ = 41 degrees (incline of the ramp)

N = 14.26kg * 9.8 m/s² * cos 41°

N = 105.47 N

So,

Fstatic = µs * (mg * cos(θ))

making µs subject of the formula and substituting already calculated vaues we get,

µs =      Fstatic

          (mg * cos(θ))

µs =    139.75 N

         105.47 N

When a car has double the speed of the truck

Momentum is calculated by multiplying the mass by the velocity. And we have masses of 1000 kg and 2000 kg and to make the momentum equal velocity needs to be inversely proportional.

Let the velocity of the car be x m/s

momentum (p) = mass * velocity

then momentum is 1000*x

1000x kgm/s

So lets the velocity of the truck be y m/s

the momentum of the truck will be 2000*y

so 2000y kgm/s

by the condition 1000x = 2000y

so on solving

x= y/2

which shows the car has double the velocity of the truck.

Answer:

9 hours

Explanation:

When the 2nd car catches up to the first, both cars will have gone the same distance.  

Distance = rate x time

Distance car 1 traveled when car 2 catches up = 90 mph(3 hr + t)

Distance car 2 traveled when it catches up to car 1 = 120t

90(3 + t) = 120t

270 + 90t = 120t

30t = 270

t = 270/30 = 9 hrs

Therefore, 12 hours after car 1 leaves the city and 9 hours after car 2 leaves the same city, they meet up.  

To prove it:

The distance moved by an object when it acted by a net force 1 N and time 3s is found to be 0.9m

According to this, an object's rate of change in velocity is directly proportional to the force used and moves in the direction of the applied force. The equation: summarises it. Mass (kg) times acceleration (m/s2) equals force (N). A constant mass item will therefore accelerate in direct proportion to the force exerted.

F = ma

acceleration = F/m => 1/5

v= u + at, u=0 (initially at rest);

v=at = distance/t = at;

S = distance => ut + 1/2at^2

the distance traveled by object in the given time 3s = acceleration x t2

The acceleration is determined by dividing the net force by the mass. An object's acceleration doubles if the net force exerted on it also doubles. Increased mass will result in a halving of acceleration. If the mass and net force are both doubled, the acceleration will remain constant.
