Question

]
a) The figure below shows a simple pendulum of mass 200 g. It is displaced from
the mean position A to the extreme position B. The potential energy at the
position A is zero. At the position B the pendulum bob is raised by 5 m.
5 m
(1) What is the potential energy of the pendulum at the position B? /
(ii) What is the total mechanical energy at point C?
0
on) What is the speed of the bob at the position A when released from B? Ims
(Take g = 10 ms 2 and there is no loss of energy.)​

Answer 1

Answer:

mgh = 200×10×5=10000

ME=U+KE

U=mgx

KE= mg(h-x)

U+KE=mg(h+x-x)

mgh =200×10×5=10000
