A lift is descending with uniform acceleration. To measure the acceleration, a person in the lift drops a coin at the moment when lift was descending with speed 6 ft/s. The coin is 5 fit above the floor of the lift at time it is dropped. The person observes that the coin strikes the floor in 1 second. Calculate from these data, the acceleration of the lift in ft/s 2. [Take g = 32 ft/s 2]
