A stone is dropped from a height $h.$ It hits the ground with a certain momentum $P.$ If the same stone is dropped from a height $100\%$ more than the previous height, the momentum when it hits the ground will change by ........... $\%$

In accordance with Newton's third law of motion
A bullet is fired from a gun. The force on the bullet is given by:
$F = 600 - 2 \times 10^5\ t$
Where $F$ is in newton and $t$ in second. The force on the bullet becomes zero as soon as it leaves the barrel. What is the average impulse imparted to the bullet?
A solid horizontal surface is covered with a thin layer of oil. A rectangular block of mass $m =0.4 kg$ is at rest on this surface. An impulse of $1.0 N s$ is applied to the block at time $t =0$ so that it starts moving along the $x$-axis with a velocity $v ( t )= v _0^{ e ^{-1 / \tau}}$, where $v_0$ is a constant and $\tau=4 s$. The displacement of the block, in metres, at $t=\tau$ is. . . . . . . Take $e ^{-1}=0.37$

A stone of mass $m$ is tied to a string of length $l$ and rotated in a circle with a constant speed $v$. If the string is released, the stone flies
