A man of mass m1 is standing on platform of mass m2 kept on a smooth horizontal surface.

Question 1

A man of mass m1 is standing on platform of mass m2 kept on a smooth horizontal surface.The man starts moving on the platform with a velocity νr relative to the platform. Find the recoil velocity of platform.

Question 2

Absolute velocity of man= νr – ν, w where ν = recoil velocity of platform.

Taking the plat form and the man as a system, net external force on the system in horizontal direction is zero. The linear momentum of the system *** constant. Initially both the man and the plat form were at rest.
