A simple pendulum with a period 7" = 3.50 s is attached to the ceiling of an elevator which is initially at rest. The acceleration due to gravity is g = 9.81 m/s2 @ Macmillan Learning Calculate the oscillation period 7up when the elevator begins to accelerate upwards with acceleration a = 2.00 m/s Calculate the oscillation period Tdown when the elevator accelerates downwards with acceleration a = 0.50 m/s2 Tdown
