If a force of $250\, N$ act on body, the momentum acquired is $125\, kg-m/s$. What is the period for which force acts on the body ......... $\sec$
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 $e ^{-1}=0.37$
$100 \,g$ of a iron ball having velocity $10 \,m/s$ collides with a wall at an angle ${30^o}$ and rebounds with the same angle. If the period of contact between the ball and wall is $0.1 \,second$, then the force experienced by the ball is ............. $\mathrm{N}$
How can we draw a two objects $FBD$ according to Newton’s third law ?
“Momentum and changes in momentum are not always in same direction”. Explain by suitable example.
