A body of mass

10 \mathrm{~g}

moving with velocity

5 \mathrm{~ms}^{-1}

collides with another body of mass

15 \mathrm{~g}

moving with

3 \mathrm{~ms}^{-1}

in the same direction. After collision if they stick and move together, the loss of kinetic energy of the system is

View answer and explanation

Correct option: B

12 \times 10^{-3} \mathrm{~J}

Option B (

12 \times 10^{-3} \mathrm{~J}

) is correct because it represents the loss of kinetic energy after the inelastic collision where the two bodies stick together.

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
