A rope ladder with a length

l

carrying a man with a mass m at its end is attached to the basket of balloon with a mass M. The entire system is in equilibrium in the air. As the man climbs up the ladder into the balloon, the balloon descends by a height h. Then the potential energy of the man

View answer and explanation

Correct option: A

Increase by

m\mathrm{g}\left( {l - h} \right)

Option A (

m\mathrm{g}\left( {l - h} \right)

) is correct because the man's potential energy increases by the difference between the ladder length and the balloon's descent.

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
