A 921kg sports car is moving rightward with a speed of 29.0m/s. The driver suddenly slams on the brakes, causing a 8347N resistive net force and the car skids to a stop. Determine the time it takes to stop the car.

1 answer

Force=ma= mass*(Vf-Vi)/time

time= mass*(Vf-Vi)/force

vf=0

solve for time.
