Question

a simple pendulum is made from a bob of mass 0.040 kg suspended on a light on a light string of length 1.4m. keeping the string taut the pendulum is pulled to one side until it has gained height of 0.10m . calculate total energy of the oscillation

Answer 1

m g h = 0.040 * 9.81 * 0.10

Answer 2

What is total energy of the oscillation and amplitude of the resulting oscillation
