An oscillating pendulum has a velocity of 2ms-1 at the equilibrium position O and velocity at same point P. Using the diagram above, calculate the height of P above O. (Take g = 10ms2)

An oscillating pendulum has a velocity of 2ms^-1 at the equilibrium position O and velocity at same point P. Using the diagram above, calculate the height of P above O. (Take g = 10ms²)

A 5.0m
B 2.0m
C 0.4m
D 0.2m
E 0.1m

The correct answer is D. 0.2m

Kinetic energy at O = P.E at P 1/2mV = mgh

h = v/2g = 0.2m
