An elevator (lift) ascends with an upward acceleration of 1.2 `ms^(-2)`.At the instant when its upward speed is 2.4 `ms^(-1)`, a loose bolt drops from the ceiling of the elevator 2.7 m above the floor of the elevator . Calculate (a) the time of flight of the bolt from the ceiling to the floor and (b)the distance it has fallen relative to the elevator shaft.
