The bob A of a simple pendulum released from `30^(@)` to the vertical hits another bobo B of the same mass at rest on a table as shown in figure. How high does the bob A rise after the collision ? Neglect the size of the bobs and assume the collision to be elastic.

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.

The bob A of a simple pendulum is released when the string makes an angle of 45^(@) with the vertical. It hits another bob B of the same meterial and same mass kept at rest on the table. If the collision is elastic, then

The bob A of a pendulum released from a height h hits head-on another bob B of the same mass of an identical pendulum initially at rest. What is the result of this collision? Assume the collisio to be elastic (see figure).

The bob of a simple pendulum of length l dropped from a horizontal position strikes a block of the same mass, placed on a horizontal table (frictionless) as shown in the diagram, the block shall have kinetic energy-

Assertion : Object A of mass collides elastically with another object B of same mass at rest and if found that A and B move perpendicular to each other after collision . Reason : Collision between A and B is not head on .

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

The bob A of a simple pendulum is released from a horizontal position A as shownin in figure. If the length of the pendulum is 1.5m , what is the speed with which the bob arrives at the lowermost point B, given that it dissipates 5% of its initial energy against air resistance ?

A pendulum bob of mass m and length L is released from angle theta with the vertical. Find (a) the speed of the bob at the bottom of the swing and (b) tension in the string at that time

Two identical ball bearings in contact with each other and resting on a frictionless table are hit heat-on by another ball bearing of the same mass moving initially with a speed V as shown in figure. If the collision is elastic, which of the following (figure) is a possible result after collision ?
