Problem #4: Use the graph below for parts A, B, and C, and the following information: A mass of 6 kg is released from rest at the negative amplitude at t=0 seconds. velocity versus time for vibrating mass on a spring velocity in meters/second 6.00 4.00 2.00 0.00 -2.00 0.5 1 1.5 2 2,5 3 3.5 -4.00 -6.00 time in seconds A. Find the spring constant for this spring. T= 2 MIK k m. (2/T) 6kg K=6. (2/2 k = p 236.87 B. Find the amplitude of this vibration. 6.00 ms/second highest paint ~0.5 seconds C. Find the maximum acceleration of the 6-kg mass during this vibration. D. Suppose we measure the period of a vibrating mass on a Hooke's Law spring at sea level, along with measuring the period of the mass vibrating as a simple pendulum at sea level. If we repeat this experiment at the top of a very tall mountain, describe what happens to the period of each (spring and pendulum): increase, decrease, or stays the same. Explain!
