A ping-pong ball strikes a wall with a velocity of 12 m/s if the collision is perfectly elastic, find the velocity of ball after impact?

View answer and explanation

Correct option: A

-12

Option A (-12) is correct because in a perfectly elastic collision, the velocity reverses direction while maintaining the same magnitude.

ball is dropped on the ground from a height of

2 {~m}

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in
