Question

A pendulum of mass m is in it's mean position, a small ball of mass m collides with it in x axis. Find the maximum height attained by pendulum after collision​

Answer 1

Answer:

As collision is elastic and colliding objects are identical therefore velocities will interchange, i.e pendulum will start moving with velocity v and at max. height it's kinetic energy will change into potential energy.

i.e.

1/2mv²=mgh

⇒h=v²/2g.

Hope it helps! :)

Explanation:

Answer 2

Explanation:

Here KE=PE

therefore h=v2/2g by putting in related equations
