C

D

Text Solution

Verified by Experts

The correct Answer is:
B
Ans. (2)
Momentum of first ball bearing is transfer to second & this momentum is finally transfer to 3rd.

A ball moving on a horizontal frictionless plane hits an identical ball at rest with a velocity of 0.5m//s . If the collision is elastic, calculate the speed imparted to the target ball, if the speed of projectile after the collision is 30cm//s .

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. Then, 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.
