A ping-pong ball strikes a wall with a velocity of 10 ms^(-1) . If the collision is perfectly elastic, find the velocity if ball after impact

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 . Show that the two balls will move at right angles to eachother, after the collision.

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.

A ball moving with a speed of 9m//s strikes an identical ball at rest, such that after the collision, the direction of each ball makes an angle of 30^(@) with the original line of motion. Find the speeds of the two balls after collision.

Prove that in a two dimensional elastic collision of a moving ball with another stationary identical ball, the two balls move perpendicular to each other after collision?

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 moving with a speed of 9ms^(-1) strikes an identical ball such that after the collision the direction of each ball makes and angle 30^@ with the original line of motion. Find the speeds of the two balls after the collision.

A ball of mass m moving with velocity V , makes a head on elastic collision with a ball of the same moving with velocity 2 V towards it. Taking direction of V as positive velocities of the two balls after collision are.

Two balls of equal masses m each undergo oblique collision. If colision is perfectly elastic, then angle between their velocities after collision is
