Simple Harmonic Motion

Questions

A mass m = 100 g is attached at the end of a light spring which oscillates on a frictionless horizontal table with an amplitude equal to 0.16 m and time period equal to 2 s.

Initially mass is released from rest at t = 0, and displacement x = − 0.16 m. The expression for the displacement of the mass at any time t is:

1) x=0.16 сos (лt +л)
2) x=0.16 cos (лt)
3) x=0.16 sin (лt +л)
4) x 0.16 cos (лt)
