Kinetic energy of a particle moving in a straight line varies with time

t

K=4 t^2

. The force acting on the particle

View answer and explanation

Correct option: A

is constant

Option A (is constant) is correct because the force is proportional to the derivative of kinetic energy with respect to position, which is constant given the kinetic energy function.

. 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
