Two fat astronauts each of mass 120 kg are travelling in a closed spaceship moving at a speed of 15 km/s in the outer space far removed from tall other material objects. The total mass of the spaceship and its contents 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 spaceship move?

A cord of length 4 m is used to connect a 100 kg astronaut to spaceship whose mass is much larger than that of the astronaut. Estimat the value of the tension in the cord. Assume that the spaceship is orbiting near earth surface. A ssume that the spaceship and th eastronaut fall on a straight line from the earth centre. The radius of the earth is 6400 km.

A cord of length h = 64m is used to connect an astronaut (m = 100 kg) to a spaceship (M > > m)which is orbiting near the earth's surface as shown in the figure. Assuming that the spaceship and the astronaut fall on a straight line from the earth's centre, then the tension in the cord is close to [R = 6400 km] <br> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/NTA_JEE_MOK_TST_19_E01_010_Q01.png" width="80%">
