Question

The pendulum of length 1m and bob mass is 5 grams released from an angle 60 degrees with the vertical. The pendulum hit a mass of 200 grams which is just the middle of the pendulum swing. what will be the velocity of mass after the pendulum hits?

Answer 1

Answer:

Length of simple pendulum =1m

Mass =1wgm=0.1kg

It is displaced through as angle of 60 for vertical

Height of pendulum at starting position = length (1−ws60)

=1(1−0.5)

=0.5m

Potential energy =mgh=0.1×10×0.5=0.55

when it is released and it reaches mean position its potential energy
