A body of mass $m=3.513 \;kg$ is moving along the $x$ - axis with a speed of $5.00 \;ms ^{-1}$. The magnitude of its momentum is recorded as  (Consider significant figures)

The force $F$ acting on a particle of mass $m$ is indicated by the force-time graph shown below. The change in momentum of the particle over the time interval from zero to $8\, s$ is   .......... $N-s$

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 $e ^{-1}=0.37$

The distance covered by a body of mass $5\,g$ having linear momentum $0.3\,kg\,m / s$ in $5\,s$ is $..........\,m$

Position-time graph for a particle of mass $100g$ is as shown in figure then impulse  acting on the particle at $t = 5$ second is ............ $N-s$
