A long spring, when stretched by x cm has a potential energy U. On increasing the length of spring by stretching to nx cm, the potential energy stored in the spring will be

View answer and explanation

Correct option: C

{n^2}U

Option C (

{n^2}U

) is correct because the potential energy is proportional to the square of the extension, so increasing the extension by a factor of 'n' increases the potential energy by a factor of n squared.

. 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
