- A block-spring oscillator on a frictionless table has k = 125N/m and block mass = 0.5kg; the block is oscillating back and forthand its initial position (i.e. when t = 0 sec) is when the springis compressed to a maximum amount of 1.25 m:
a) In 10 seconds how many times doesthe block oscillate back and forth?
b) What are the maximum kinetic energyand the maximum velocity of the block?
c) Where is the block located on the xaxis when its KE is ¾ of the maximum PE?
d) What is the acceleration of theblock when its KE is ¼ the maximum KE?
