Show your complete solution. Write your final answer after the question.1. A pendulum in Brussels swings for a period of 3 seconds. Compute the length of the pendulum. At another location, the length of the pendulum is known to be 2 meters and the time of the pendulum is estimated to be 2.839 seconds. What is the gravitational acceleration at that location? Ans:_______2. Calculate the response of the tip of a leg bone to the initial velocity v0=0.8 meter per second. and zero initial displacements (this would correspond to the vibration-induced while landing on your feet, with your knees locked from a height of 18 mm) and plot the response. Human legs have an approximate natural frequency of about 25 Hz on average when in their most natural (knee-locked) position and a damping ratio of 0.224. Lastly, determine the maximum acceleration encountered by the leg, assuming no damping. Ans:_________
