A 0.80 kg mass is attached to a light spring with a force constant of 23.9 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
