You are designing an elevator for a hospital. The force exerted on a passenger by the floor of the elevator is not to exceed 1.50 times the passenger's weight. The elevator accelerates upward with constant acceleration for a distance of 3.6 m and then starts to slow down.
What is the maximum speed of the elevator?
Express your answer in meters per second.
