1.	Two fat astronauts each of masses 120 kg are travelling in a closed spaceship moving at a speed of 15 m/s in the outer space far removed from all other material objects.The total mass of the spaceship including the astronauts is 660 kg.If the astronauts do slimming exercise and thereby reduce their masses to 90 kg each,with what velocity will the spaceship move?
Answer» So, Let Me CLEAR One THING... THE SYSTEM OS CLOSED... Hence The Mass Loosed by Them Will Remain in Spaceship only.. So, It will move with the same VELOCITY it was moving... So, The Answer is 15 m/s :)
