Paragraph : A spaceship traveling east flies directly over the head of an inertial observer who is at rest on the Earth's surface. The speed of the spaceship can be found from this relationship: `sqrt(1-v^(2)//c^(2))=1//2`.

A

5m

B

20m

C

10m

What is the minimum work that has to be performed to bring a spaceship of mass m=2.0*10^3kg from the surface of the Earth to the Moon?

A space-ship is launched into a circular orbit close to the Earth,s surface. What additional speed should now be imparted to the spaceship so that it overcome the gravitational pull of the Earth. Take kinetic energy of the space-ship, K = total energy of space-ship = (GMm)/(2R) where m = mass of space-ship, M= mass of the earth and R = radius of the earth.

Einstein in 1905 proppunded the special theory of relativity and in 1915 proposed the general theory of relativity. The special theory deals with inertial frames of reference. The general theory of relativity deals with problems in which one frame of reference. He assumed that fixed frame is accelerated w.r.t. another frame of reference of reference cannot be located.
