Question

A 20 g particle is oscillating simple harmonically with a period of 2 second and maximum kinetic energy 2 J. The total mechanical energy of the particle is zero. Write the following — 

(a) Amplitude of oscillation

(b) Potential energy as a function of displacement x relative to mean position.

Answer 1

(a) m = 20 g = 20 × 10^–3 kg

T = 2s

K_max = 2 J
