Satellite A in orbit around the Earth has a mass of 500 kg. Satellite B, with a mass of 750 kg, is placed in an orbit with the same radius as that of Satellite A. The speed of B is (a) 1.5 times slower than A
(b) 2.25 faster than A
(c) the same as A
(d) 1.5 times faster than A

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
