## What is the momentum of a 2000 kg truck that moves at 10 ms?

Momentum before the collision is p=mv=2000⋅10=20,000 kgms−1 .

## When a large truck collides with a small car which undergoes the greater change in momentum?

because force and time is same for both the truck as well as car; so the change in momentum of truck is equal and opposite to change in momentum of car.

## Which has a greater momentum a 1000 kg truck at rest or a 100 kg bicycle in motion?

Taking the formula for momentum to be p=mv this is the mass multiplied by the velocity. Although the semi truck certainly has a larger mass, it is not in motion and therefore does not have any momentum. The bicycle however has both mass and velocity and therefore has the larger momentum of the pair.

## Is momentum calculated with kg?

In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second.

## What is the formula for the change in momentum of a collision?

The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.

## What happens when a smaller object collides with a larger object?

In accord with Newton’s second law of motion, the acceleration of an object is dependent upon both force and mass. Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

## What is the formula for the change in momentum after a collision?

In collisions between two isolated objects momentum is always conserved. Kinetic energy is only conserved in elastic collisions. We always have m1v1i + m2v2i = m1v1f + m2v2f. Only for elastic collisions do we also have ½m1v1i2 + ½m2v2i2 = ½m1v1f2 + ½m2v2f2.

## What is the momentum of a 1500 kg car?

Therefore p=1500*20 = 30,000 kg m/s.

## Which has the greatest momentum?

A less massive object can never have more momentum than a more massive object. Two identical objects are moving in opposite directions at the same speed. The forward moving object will have the greatest momentum. An object with a changing speed will have a changing momentum.

## What is two body collision?

In physics, an elastic collision is an encounter (collision) between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy.

## What is the momentum of 1000 kg car moving northward at 20 m?

p = mv = (1000kg)(20m/s) = 20000 kg m/s, northward • c.

## What is the momentum of a 1000 kg object that is not moving?

The momentum of any object that is at rest is 0.

## What is the average braking force of a 1000 kg truck moving at 10 m s that brakes to a stop in 5s?

Answer: The average braking force is 2000 N.

## Which vehicle has smaller momentum a 2000 kg car moving at 30m s or a 4000 kg light truck moving at 15m s?

In physics terms, we say that the truck has greater momentum. Velocity is a term that refers to both speed and direction. For our purposes we will assume that the vehicles are traveling in a straight line. In that case, velocity and speed are the same.
