A bungee jumper undergoes simple harmonic motion with amplitude 7.9m and frequency 0.110Hz . Assume the bungee jumper follows the simple harmonic motion equation x=Acos(?t).
Part A Determine the bungee jumper's velocity at 0.25 s.
Part B Determine the bungee jumper's velocity at 0.50 s.
Part C Determine the bungee jumper's velocity at 1.0 s.
