A 50 g mass is attached to a securely clamped spring. The mass is pulled downwards by 16 mm and released, which causes it to oscillate with s.h.m. of time period of 0.84 s.
a. Calculate the frequency of the oscillation.
b. Calculate the maximum velocity of the mass.
c. Calculate the maximum kinetic energy of the mass and state at which point in the oscillation it will have this velocity.
d. Write down the maximum gravitational potential energy of the mass (relative to its equilibrium position). You may assume that the damping is negligible.
