Question

Find out the velocity of the pendulum bob at the mean position release it from three different height and show kinetic energy increases as the height increases.

Answer 1

Answer:

mark me as brainlist ❣️❣️❣️

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
