Two smooth balls A and B, each of mass m and radius R, have their centre at (0,0,R) and (5R,-R,R) respectively, in a coordinate system as shown. Ball A, moving along positive x-axis, collides with ball B. Just before the collision, speed of ball A is 4m/s and ball B is stationary. The collision between the balls is elastic. Velocity of the ball A just after the collsion is

Two smooth balls A and B, each of mass m and radius R, have their centers at (0, 0, R) and at (5R, -R, R) respectively, in a coordinate system as shown. Ball A, moving along positive x axis, collides with ball B. Just before the collision, speed of ball A is 4m/s and ball B is stationary. The collision between the ball is elastic. Impulse of the force exerted by A and B during the collision, is equal to

Just before the collision, speed of ball 'A' is 4m//s and ball 'B' is stantionary. The collision Impluse of the force exerted by 'A' on 'B' during the collision is equal to

Two smooth balls A and B , each of mass m and radius R , have their centres as shown in fig. Ball A , moving along positive x-axis, collides with ball B . Just before the collision, speed of ball 'A' is 4m//s and ball 'B' is stantionary. The collision Coefficient of restitution during the collision is changed to (1)/(2) , keeping all other parameters unchanged. What is the velocity of the ball 'B' after the collision.

A glass ball collides with an identical ball at rest with v_(0)=2 m/sec. If the coefficient of restitution of collision is e = 0.5, find the velocities of the glass balls just after the collision.

An iron ball A collides with another stationary iron ball B If the ratio of radii of the balls is n = 2, find the ratio of their speeds just after the collision (e = 0.5)

A ball moving with a speed of 10" m s"^(-1) strikes an identical ball such that after the collision the direction of each ball makes an angle 45^(@) with the original line of motion. Find the speeds of the two balls after 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.
