A girl of mass 50kg jumps out of a rowing boat of mass 300 kg on to the bank, with a horizontal velocity of 3 m/s.
With what velocity does the boat begin to move backwards?

Given that,

Mass of a girl, m  = 50 kg

Mass of the boat, m' = 300 kg

Speed of girl, v = 3 m/s

To find,

The velocity with which the boat begin to move backwards.

Solution,

Let the velocity be v'. Using the conservation of momentum to find it. It is given by :

So, the velocity moves backward with a speed of 0.5 m/s.
