Two identical ball bearings in contact w...

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 ?

A

B

C

D

(b) When two bodies of equal masses colides elastically their velocities are interchanges. When ball 1 collides with ball-2 then velocity of ball-1. `v_(1)` becomes zero and velocity of ball-2, `v_(2)` becomes v,i.e. similarity
When ball 2 collides will ball 3
`{:(,v_(1)=0,Rightarrow v_(2)=v),(,v_(2)=0,v_(3)=v):}`

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, figure,. If the collision is elastic, which of the following is a possible result after collisioin?

Two ball bearings of mass m each moving in opposite directions with same speed v collide head on with each other. If the collision is perfectly elastic, what will be the outcome of the collision ?

A ball is moving with velocity 2m//s towards a heavy wall moving towards the ball with speed 1m//s as shown in figure. Assuming collision to be elastic, find the velocity of ball immediately after the collision.

In the figure shown, the two identical balls of mass M and radius R each, are placed in contact with each other on the frictionless horizontal surface. The third ball of mass M and radius R/2, is coming down vertically and has a velocity = v_(0) when it simultaneously hits the two balls and itself comes to rest. The each of the two bigger balls will move after collision with a speed equal to

STATEMENT - 1 : Two identical balls B and C lie on a horizontal smooth straight groove so that they are touching. A third identical ball A moves at a speed v along the groove. And collides with B as shown in figure. If the collisions are perfectly elastic, then after the collision, balls A and B will come to rest and ball C moves with velocity v to the right. because STATEMENT - 2 : In an elastic collision, linear momentum and kinetic energy are both conserved.

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).

A ball of mass m makes an elastic collision with another identical ball at rest. Show that if the collision is oblique, the bodies go at right angles to each other after collision.
