Explanation / Answer

(a) Whatis the period of simple harmonic motion for this pendulum if it ishanging in an elevator accelerating upward at 4.00 m/s2?
s
T=2*3.148/9.8+4=4.7815sec
(b) What is its period if the elevator is accelerating downwardat 4.00 m/s2?
s
T=2*3.148/9.8-4=7.375sec
(c) What is the period of simple harmonic motion for the pendulumif it is placed in a truck that is accelerating horizontallyat 4.00 m/s2?
s
T=2*3.148/[(9.82+42]1/4=5.460sec
