A sphere of mass M moving with velocity collides elastically with another of mass ‘m’ at rest. After collision their final velocities are

{V_1}\,\,and\,\,{V_2}

then the value of

\,{V_2}

is

View answer and explanation

Correct option: D

\frac{{2u}}{{1 + \frac{m}{M}}}

Option C (

\frac{{2u}}{{1 + \frac{M}{m}}}

) is correct because it is derived from conservation of momentum and kinetic energy in an elastic collision.

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
