The elevator starts from rest at the first floor of the

 building. It can accelerate at 5 ft/s and then decelerate at 2ft/s

Determine the shortest time it takes to reach a floor

40 ft above the ground. The elevator starts from rest and

then stops. Draw the a–t, v–t, and s–t graphs for the motion.
