A car accelerates uniformly from rest at the rate of 2.0 m/s2 for 6.0 s. It then maintains a constant speed for 0.50 min. Finally, the brakes are applied and the vehicle slows down at a uniform rate and comes to rest in 5.0 s. Find (a) the maximum speed of the car and (b) the total displacement. (12 m/s, 4.3 x 102 m)
