Conservation of Momentum

A boy of mass $50 \mathrm{k}\mathrm{g}$ jumps out of a rowing boat of $300 \mathrm{k}\mathrm{g}$ on to the bank with a horizontal velocity of $3 \mathrm{m} {\mathrm{s}}^{-1}$. With what velocity does the boat begin to move backwards?

A bullet of mass $10 \mathrm{g}$ travelling at $200 \mathrm{m} {\mathrm{s}}^{-1}$strikes and remains embedded in a $2 \mathrm{k}\mathrm{g}$ freely suspended wooden block. What is the velocity acquired by the block?

A gun of mass $\mathrm{M} \mathrm{kg}$ fires a shell of mass $1.5 \mathrm{kg}$ with a velocity of $150 \mathrm{m} {\mathrm{s}}^{-1}$ and recoils with a velocity of $1.5 \mathrm{m} {\mathrm{s}}^{-1}$. Calculate the mass of the gun.

A gun of mass $1000 \mathrm{kg}$ fires a shell of mass $2 \mathrm{kg}$ with a velocity of $200 \mathrm{m}/\mathrm{s}$. Calculate the velocity of recoil of the gun.

ISRO(Indian space research organisation) started its project of SLV (Satellite Launch Vehicle) in early $1970$s. This project was headed by A.P.J. Abdul Kalam. A Satellite Launch Vehicle is used for launching of satellites. This project had is first experiment flight of SLV$-3$ in August $1979$ which was partially successful. But now India has a capacity to design, manufacture and launch its own SLV's along with the satellite. Thanks to the hard and dedicated work of ISRO.
