# What is the total momentum when a 5 kg ball is moving to the right at 4 m/s and collides with another 5 kg ball that is stationary?

## What is the total momentum when a 5 kg ball is moving to the right at 4 m/s and collides with another 5 kg ball that is stationary?

The fact that momentum and kinetic energy are conserved mean that the total momentum after the collision will be 20 kgms−1 and the total kinetic energy after the collision will be 40 J .

## How do you find the velocity of a ball after a collision?

If two particles are involved in an elastic collision, the velocity of the second particle after collision can be expressed as: v2f=2⋅m1(m2+m1)v1i+(m2−m1)(m2+m1)v2i v 2 f = 2 ⋅ m 1 ( m 2 + m 1 ) v 1 i + ( m 2 − m 1 ) ( m 2 + m 1 ) v 2 i .

What is the change in momentum formula?

The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v.

### Which has a greater momentum a truck with a mass of 2250 kg moving at a speed of 25 m/s or a car with a mass of 1210 kg moving at a speed of 51 m s?

Which has a greater momentum—a truck with a mass of 2250 kg moving at a speed of 25 m/s or a car with a mass of 1210 kg moving at a speed of 51 m/s? The car has a greater momentum.

### How do you find total momentum?

Since the two colliding objects travel together in the same direction after the collision, the total momentum is simply the total mass of the objects multiplied by their velocity.

How do you find the speed of an object after a collision?

In a collision, the velocity change is always computed by subtracting the initial velocity value from the final velocity value. If an object is moving in one direction before a collision and rebounds or somehow changes direction, then its velocity after the collision has the opposite direction as before.

#### How do you find speed in momentum?

Speed=momentum /mass.

#### What is the change in momentum of the ball?

Since the initial momentum of the ball is zero while being at rest, the momentum being transferred will be equal to the final momentum of the ball. This change in momentum is the result of a force imparted by the club on the ball (2nd law) acting over a given duration of time.

What is the mass of a mallard duck whose speed is 8.9 m/s and whose momentum has a magnitude of 12 kg ⋅ m s?

Therefore, the mass of the mallard duck m=1.23kg.

## What is the speed of a rubber ball moving?

A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. The magnitude of the momentum of the rubber ball

## What is the momentum change of a rubber ball?

The momentum change of an object is equal to the impulse acting on it A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. The magnitude of the momentum of the rubber ball

What happens to the momentum when an object hits a wall?

The momentum change of an object is equal to the impulse acting on it A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. The magnitude of the momentum of the rubber ball remained the same Two objects move separately after colliding, and both the total momentum and total kinetic energy remain constant.

### What is the relationship between velocity and momentum after a collision?

Before the collision, the two objects were moving at velocities equal in magnitude but opposite in direction. After the collision, the less massive object had gained momentum. What are the SI units for momentum? kg*m/s A 20 kg shopping cart moving at a velocity of 0.5 m/s collides with a store wall and stops. The momentum of the shopping cart
