A1800-kg spacecraft is in a 700x1200 km altitude earth orbit. a spacecraft has a re-startable onboard propulsion system with a thrust of 12kn and specific impulse of 275s. assuming the thrust vector remains aligned with the velocity vector and that the burn time is 75 seconds, determine: a) mass of propellant expended b) eccentricity of the new orbit c) the new apogee altitude

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

dang that balls went far

  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.
