Question

What is the speed of 2 kg metallic bob at the mean position in simple pendulum when released from extrme position of 0.5 m height

Answer 1

Explanation:

Given that,

Height h =10 cm

Now,

Kinetic energy at mean position = potential energy at maximum height

v=

2×9.8×0.1

v=1.4m/s

Hence, the velocity of the bob is 1.4 m/s
