Question

 

A 1200-kg truck travels in a straight line and has a speed 25 m/s in the +x direction when the driver hits the brakes. The truck slows down to 5 m/s in 10 s. Assume that the net force on the truck is constant.

  1. What is the force by the road and air on the truck as it slows down?
  2. What is the displacement of the truck during this time interval?
