Solving problems (basic level)

The driver of a car going 90.0 km/h suddenly sees the lights of a barrier 40.0 m ahead. It takes the driver 0.75 s to apply the brakes, and the average acceleration during braking is 10.0 m/s2. a. Determine whether the car hits the barrier. b. What is the maximum speed at which the car could be moving and not hit the barrier?

A truck is stopped at a stoplight. When the light turns green, the truck accelerates at 2.5 m/s2. At the same instant, a car passes the truck going 15 m/s. Where and when does the truck catch up with the car?
