Question

A 0.68 kg mass is attached to a light spring with a force constant of 36.9 N/m and set into oscillation on a horizontal frictionless surface. If the spring is stretched 5.0 cm and released from rest, determine the following.

(a) maximum speed of the oscillating mass
  
m/s

(b) speed of the oscillating mass when the spring is compressed 1.5 cm
  
m/s

(c) speed of the oscillating mass as it passes the point 1.5 cm from the equilibrium position
  
m/s

(d) value of x at which the speed of the oscillating mass is equal to one-half the maximum value

m

I want details.
