An electric vehicle starts from rest and accelerates at a rate of 1. 9 m/s2 in a straight line until it reaches a speed of 30 m/s. The vehicle then slows at a constant rate of 1. 4 m/s2 until it stops. (a) How much time elapses from start to stop? (b) How far does the vehicle move from start to stop.
