To study the effects of acceleration on the period of oscillation, a student puts a grandfather clock with a 0.9929-m-long pendulum inside an elevator. Find the period of the grandfather clock (a) when the elevator is stationary, (b) when the elevator is accelerating upward at 1.50 m/s 2 , (c) when the elevator is accelerating downward at 1.50 m/s 2 , (d) when the cable on the elevator breaks and the elevator simply falls, and (e) when the elevator is moving upward at a constant speed of 5.00 m/s.
