Question

A simple pendulum consists of a string of length
50.0 cm and a pendulum bob of mass 10 g. The
string hangs vertically from a fixed point o with
the pendulum bob attached to its lower end at
point P (Figure 6.17).

A Figure 6.17
The pendulum bob is displaced to point R, 2.0 cm
above P and released from rest. Assuming air
resistance is negligible, calculate the
(a) gain in potential energy of the pendulum

a)
(b) kinetic energy of the bob at point Q, 0.5 cm
above P.
