If kinetic energy of a body is increased by $300\%$ than percentage change in momentum will be

The same retarding force is applied to stop a train. The train stops after $80 m$. If the speed is doubled, then the distance will be

The kinetic energy $k$ of a particle moving along a circle of radius $R$ depends on the distance covered $s$ as $k = a{s^2}$ where $a$ is a constant. The force acting on the particle is

If the momentum of a body is increased by $100\%$, then the percentage increase in the kinetic energy is ............ $\%$

In the figure shown all the surfaces are frictionless, and mass of the block, $m = 1\, kg$. The block and wedge are held initially at rest. Now wedge is given a horizontal acceleration of $10\, m/s^2$ by applying a force on the wedge, so that the block does not slip on the wedge. Then work done by the normal force in ground frame on the block in $\sqrt 3 $ seconds is ......... $J$

If the momentum of a body is increased $n$ times, its kinetic energy increases
