An elevator ascends with an upward acceleration of 4.0-ft/s2. At the instant its upward speed is 8.0 ft/s, a loose bolt drops from the ceiling of the elevator 9.0 ft from the floor. Calculate (a) the time of flight of the bolt from ceiling to floor and (b) the distance it has fallen relative to the elevator shaft.
