An elevator ascends with an upward acceleration of 1.75 m/s^2. At the instant its upward speed is 2.0 m/s, a loose bolt dropsfrom the ceiling of the elevator 3.5 m from the floor.
Calculate the time of flight of the bolt from the ceiling tothe floor. Assume that the elevator continues its upward acceleration. (Use a frame reference fixed with respect to the elevator shaft)
