Answer:
The change in the car's momentum is equal to -8910 kgm/s.
Explanation:
Given that,
The mass of a car, m = 990 kg
Initial speed, u = 22 m/s
Final momentum, v = 13 m/s
We need to find the change in the car's momentum. The change in momentum of the car is given by :
So, the required change in the car's momentum is equal to -8910 kgm/s.
