A car is to be hoisted by elevator to the third floor of a parking garage, which is 36 ft above the ground. If the elevator can accelerate at 0.7 ft/s2, decelerate at 0.2 ft/s2, and reach a maximum speed of 8 ft/s, determine the shortest time to make the lift, starting from rest and ending at rest. Express your answer using three significant figures and include the appropriate units.
