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/s2,
(c) When the elevator is accelerating downward at 1.50 m/s2,
(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.
