A ball is thrown with a velocity of 6m/s vertically downwards from a height H=3.2m above a horizontal floor. If it rebounds back to same height then coefficient of restitution e is

\left[ {g = 10\mathrm{ }m/{s^2}} \right]

View answer and explanation

Correct option: D

0.8

Option D (0.8) is correct because the coefficient of restitution is the ratio of the final and initial velocities, which can be calculated from the given heights.

. 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
