Question

(a) The figure below shows a simple pendulum of mass 20 g. It is
displaced from position A to B. If the potential energy at position A is
zero and it raises by 10 m at extreme position B calculate :
(i) What is P. E. at position B?
Migh= 20x 10x10= 2000]
(ii) What is total mechanical
B
10m
A
energy at position C?
righ
(iii) What is the speed of bob at the position A when released
from position B ? (g=10ms )
