A2,000-kg test car, traveling 60 m/s hits a brick wall. using motion pictures, the time involved is determined to be 0.050 s. what is the change in momentum of the car?

The change in momentum is -120000.

Step-by-step explanation:

Given : A 2,000-kg test car, traveling 60 m/s hits a brick wall. Using motion pictures, the time involved is determined to be 0.050 s.

To find : What is the change in momentum of the car?        

Solution :

The mass of the car is m=2000 kg

The initial velocity of the car is

A car hits the wall,

Change in momentum is

Substitute the value,

The change in momentum is -120000.
