The position vs time graph below shows the motion of an oscillating mass and spring system. The mass attached at the end of the spring is m = 200 g. This graph can be described using the equation:
x(t) = xm sin(wt + φ)
a) Find values of xm, w, and φ.
b) Find the total energy at the equilibrium position
c) Find the total energy at the maximum displacement.
d) How long does the block take to complete 5 cycles of its motion ?
