This question has Statement I and Statement II. Of the four choices given after the statements, choose the one that best describes the two statements.

Statement I A point particle of mass

m

moving with speed

v

collides with stationary point particle of mass

M

. If the maximum energy loss possible is given as

f\left( {\frac{1}{2}m{v^2}} \right),\,

then

f = \left( {\frac{m}{{M + m}}} \right)

Statement II Maximum energy loss occurs when the particles get stuck together as a result of the collision.

View answer and explanation

Correct option: D

Statement I is false, Statement II is true

Option D is correct. Statement I is false because the maximum energy loss is f = (M/(M+m)), and Statement II is true because maximum energy loss occurs when the particles stick together.

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
