An elevator is descending with uniform acceleration.To measure the acceleration, a person in the elevator drops a coin at momen the elevator strts. The coin is 6 ft asbove the floor of the elevator at the time it is dropped. The person observes that the coin strikes the floor in 1 second. Calculate these dta the acceleration of the elevator.

An elevator (lift) ascends with an upward acceleration of 1.2ms^-2 . At the instant when its upward speed is 2.4 ms^-1 , a loose bolt drops from the ceiling of the elevator 2.7m 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 relaative to the elevator shaft.

A person standing oin the floor of an elevator drops as coin. The coin reaches the floor of the elevator in a time t_1 if the elevator is stationary and in the t_2 if it is moving uniformly. Then
