A frictionless oscillator is composed of a 350 N/m spring and a block of mass m. It is set into motion such that at time t = 0, the block is at equilibrium (x 0 = 0) and is moving in the positive x-direction at 16 cm/s. It oscillates at angular frequency ω = 4.4 s − 1.

a) Determine the mass of the block.

b) Determine the energy of the oscillation.

c)Determine the amplitude of the oscillation.

d) Determine the phase constant. You may use either the sine or cosine form; indicate your choice clearly.

e) Determine the speed of the block when it is 1.2 cm from equilibrium.
