In a test the total braking force on the car of mass 1000kg was measured on a straight, level road. The figure below shows the resultant force on the car as a function of time from the instant the brakes were apploed (t=0s). The car came to a stop after 10s.
a) what is the magnitude of the change in momentum of the car from 0 to 10 seconds?
b) what was the intial speed of the car at t=0s?
The Attempt at a Solution
I'm not sure what to apply/where to start
Somebody please guide me through?
Thanks in advance!
