Question

A 50 kg man is standed on the end of a 25m long boat he stsrted running towords towords the other end on reaching the other end his velocity 2ms-1 if mass of the boart is 200 kg find the velocity of the boat is in ms-1

Answer 1

final velocity of boat be v.

So velocity of man with respect to ground is 2+v

As Center-of-mass of system should remain at rest, in absence of external force,

50(2+v)+200v=0⟹v=− 52

m/s

negative sign idicates that the velocity of boat is in opposite direction to that of the man.
