Once a satellite has been launched into orbit, the only force governing its motion is the force of ______ .

A rocket is fired upwards, its engine explodes fully in 12 s. The height reached by the rocket as calculated from its velocity - time graph is

The satellites when launched from the earth are not given the orbital velocity initially, a multistage rocket propeller carries the spacecraft up to its orbit and during each stage rocket has been fired to increase the velocity to acquire the desired velocity for a particular orbit. The last stage of the rocket brings the satellite in circular/elliptical (desired) orbit. Consider a satellite of mass 150 kg in a low circular orbit. In this orbit, we cannot neglect the effect of air drag. This air opposes the motion of satellite and hence the total mechanical energy of earth-satellite system decreases. That means the total energy becomes more negative and hence the orbital radius decreases which causes the increase in KE When the satellite comes in the low enough orbit, excessive thermal energy generation due to air friction may cause the satellite to burn up. Based on the above information, answer the following questions. It has been mentioned in the passage that as r decreases, E decreases but K increases. The increase in K is [ E = total mechanical energy, r = orbital radius, K= kinetic energy ]

Liquid fuel is burnt in a rocket and its exhaust gas is rejected from its tail at a velocity of 10km//s . The force acting on the rocket is 2xx10^(4)N . At what rate the liquid fuel is burnt?

If due to air drag, the orbital radius of the earth decreases from R to R-/_\R, /_\Rlt ltR , then the expression for increase in the orbital velocity /_\v is

A launching pad with a spaceship is moving along a circular orbit of the moon, whose radius R is triple that of moon Rm . The ship leaves the launching pad with a relative velocity equal to the launching pad's initial orbital velocity vec(v)_(0) and the launching pad then falls to the moon. Determine the angle theta with the horizontal at which the launching pad crashes into the surface it its mass is twice that of the spaceship m .

A rocket is fired upwards. Its velocity versus time graph is shown in the figure-1.131. The maximum height reached by the rocket is:

A satellite is orbiting around the earth in a circular orbit and in this orbit magnitude of its acceleration is a_1 . Now a rocket is fired in the direction of motion of satellite from the satellite due to which its speed instantaneously becomes half of initial, just after the rocket is fired acceleration of satellite has magnitude a_2 . Then the ratio (a_(1))/(a_(2)) is (Assume there is no external force other than the gravitational force of earth before and after the firing of rocket from the satellite)
