Question
What is the velocity of the bob of a simple pendulum at its mean position, if it is able to rise to vertical height of 10 cm? (g=9.8 )
The correct answer is:
The bob possess kinetic energy at its mean position which gets converted to potential energy at height. But the total energy remains converted.
Hence, we have
KE=PE
Let velocity of the bob at mean position be be its mass, then we have
Putting g
