Question

An oscillating pendulum has a velocity of( 2ms^1) at the equilibrium position O and the velocity at the same point P. Using the diagram above, calculate the height of P above O. [take g=10m/s^2].​

Answer 1

Answer:

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

Kinetic energy at O = P.E at P 1/2mV = mghh = v/2g = 0.2m.
