Question

There is a spring oscillator, with mass of 0.01kg,
stiffness factor as 0.49 N·m-1, at t = 0, the small ball
pass through the place of xn=0.04m and moves
along x axis in positive direction at the speed of
0.21 m-s-l. Try to find the followings of spring
oscillator:
(1) Amplitude;
(2) Initial phase:
(3) The equation of vibration​
