What is velocity of the bob of pendulum at it's
mean position it is able to rise to vertical
height of 10 cm
take g = 9.8 m/s)​ I will mark brainliest answer fast please

Answer 1

Answer:

Vertical height of the bob = 10cm (Given)

Kinetic energy of the bob at mean position = Potential energy of the bob at the highest position.

Thus,

KE = 1/2mv² = mgh

Therefore,

v = √2gh

v = √ 2 × 9.8 × 0.1

= 1.4

Thus, the velocity of the bob is 1.4 m/s.
