You are designing an elevator for a hospital. The force exerted on a passenger by the floor of the elevator is not to exceed 1.60 times the passenger's weight. The elevator accelerates upwards with constant acceleration for a distance of 3.0 m and then starts to slow down. What is the maximum speed (in ms^(-1) ) of the elevator?

An elevator without a ceiling is ascending up with an acceleration of 5 ms^-2. A boy on the elevator shoots a ball in vertical upward direction from a height of 2 m above the floor of elevator. At this instant the elevator is moving up with a velocity of 10 ms^-1 and floor of the elevator is at a height of 50 m from the ground. The initial speed of the ball is 15 ms^-1 with respect to the elevator. Consider the duration for which the ball strikes the floor of elevator in answering following questions. ( g=10 ms^-2 ) 1. The time in which the ball strikes the floor of elevator is given by
