A 4.0kg mass is attached to a spring that has a spring constant, k =2500 N/m, and is resting on a frictionless horizontalsurface. The spring is stretched by pulling on the mass untilthe amount of potential energy in the spring is 4.5 J. Theblock is then released and oscillates in simple harmonicmotion.
a. What is theamplitude of the oscillation?
b. What is the maximum velocity of the block?
c. How longdoes it take for the block to go from maximum spring length tominimum spring length?
d. What is the velocity of the mass when it is 1.5 cmfrom the spring's equilibrium point?
