The bob of a simple pendulum (mass m and length l ) dropped from a horizontal position strikes a block of the same mass elastically placed on a horizontal frictionless table. The K.E. of the block will be

If a simple pendulum of mass m is released from a horizontal position, find the tension in the string as a function of the angle theta with the horizontal.

The bob A of a pendulum released from horizontal to the vertical hits another bob B of the same mass at rest on a table as shown in figure. If the length of the pendulum is 1m, calculate (a) the height to which bob A will rise after collision. (b) the speed with which bob B starts moving. Neglect the size of the bobs and assume the collision to be elastic.
