Two identical ball bearings in contact with each other and resting on a frictionless table are hit head-on by another ball bearing of the same mass moving initially with a speed V. If the collision is elastic, which of the following (Fig. 6.14) is a possible result after collision ?

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

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 the figure. If the length of the pendulum is 1m, calculate the height to which bob A will rise after collision.

A ball of mass m, moving with a speed 2v_0 collides inelastically (e>0) with an identical ball at rest. Show that for head-on collision, both the balls move forward.

Two fixed identical conducting plates (alpha and beta) , each of surface areas S are charged to -Q and q, respectively, where Q>q>0. A third identical plate (y), free to move is located on the other side of the plate which charge q at a distance d. The third platea in released and colides with the plate beta . Assume the collision is elastic and the time of collision is sufficient to redistribute charge amongest beta and gamma . Find the charges on beta and gamma after the collision.

The bob A of a pendulum released from 30^@ to the vertical hits another bob B of the same mass at rest on a table as shown in Fig. 6.15. How high does the bob A rise after the collision ? Neglect the size of the bobs and assume the collision to be elastic.

Two identical particles of mass m carry a charge Q, each. Initially one is at rest on a smooth horizontal plane and the other is projected along the plane directly towards first particle from a large distance with speed v. The closest distance of approach be .
