Momentum

Consider two skaters who began at a rest and then pushed off against each other on ice with reduced friction. The woman weighs $45 \mathrm{kg}$ whereas the man weighs $60 \mathrm{kg}$ The woman is moving away at a speed of $4 \mathrm{m}/\mathrm{s}$. What is man’s recoil velocity?

Which of the following is given by the product of mass and velocity of an object?

Which of the following represents the linear momentum of a system with mass $m$ and velocity $v$?

Linear momentum can be defined as :

Linear momentum can be defined as the product of mass and velocity of the object.

Explain linear momentum with some examples.

A body just dropped from a tower explodes into two pieces of equal mass in mid-air. Which of the following is not possible?

Two bodies of masses $\mathrm{m}$ and $4 \mathrm{m}$ are moving with equal Kinetic energies. The ratio of their linear momentum is
