Question

An object with mass 0.3kg is acted on by an elastic restoring force with force constant 75N/m. The object is set into oscillation with an initial potential energy of 0.1 J and an initial kinetic energy of 0.25 J.

part A: what is the amplitude of oscillation?

part B: what is the value of the phase angle f if the initial velocity is positive and the initial displacement is negative?

a) 0.564 rad b) 3.93 rad c) 0.785 rad d) 4.15 rad e) 1.01 rad f) 3.71 rad
