Consider two satellites A and B of equal mass m, moving in the same circular orbit of radius r around the earth E but in opposite sense of rotation and therefore on a collision course (see figure) (i). In terms of G,M_(e) m and r find the total mechanical energy E_(A)+E_(B) of the two satellite plus earth system before collision (ii). If the collision is completely inelastic so that wreckage remains as one piece of tangled material (mass=2m) find the total mechanical energy immediately after collision. (iii). Describe the subsequent motion of the wreckage.

An artificial satellite (mass m) of a planet (mass M) revolves in a circular orbit whose radius is n times the radius R of thhe planet in the process of motion the satellite experiences a slight resistance due to cosmic dust. Assuming the force of resistance on satellite to depend on velocity as F=av^(2) where 'a' is a constant caculate how long the satellite will stay in the space before it falls onto the planet's surface.

A satellite of mass m is in an elliptical orbit around the earth of mass M(M gt gt m) the speed of the satellite at its nearest point ot the earth (perigee) is sqrt((6GM)/(5R)) where R= its closest distance to the earth it is desired to transfer this satellite into a circular orbit around the earth of radius equal its largest distance from the earth. Find the increase in its speed to be imparted at the apogee (farthest point on the elliptical orbit).
