A block of mass $5 kg$ moves along the $x$-direction subject to the force $F=(-20 x+10) N$, with the value of $x$ in metre. At time $t=0 s$, it is at rest at position $x=1 m$. The position and momentum of the block at $t=(\pi / 4) s$ are
When a $4 \,kg$ rifle is fired, the $10 \,g$ bullet receives an acceleration of $3 \times 10^6 \,cm / s ^2$. The magnitude of the force acting on the rifle (in newton) is ............
The time in which a force of $2 \,N$ produces a change of momentum of $0.4\,kg - m{s^{ - 1}}$ in the body is ......... $\sec$
In accordance with Newton's third law of motion
