a 1.5-kg object is attached to an ideal massless spring with a spring constant of 20 nN/M OSCILLATES on horizontal, frictionless trackA . At time t = 0.00 s, the mass is released from rest at x = 10.0 cm. (That is, the spring is stretched by 10.0 cm.)
(a) Find the frequency of the oscillations.
(b) Determine the maximum speed of the mass.
