(a) What is the period of simple harmonicmotion for this pendulum if it is hanging in an elevatoraccelerating upward at 7.00m/s2?
s
(b) What is its period if the elevator is accelerating downward at7.00 m/s2?
s
(c) What is the period of simple harmonic motion for the pendulumif it is placed in a truck that is accelerating horizontally at7.00 m/s2?
