Arocket is continuously firing its engines as t accelerates away from earth. for the first kilometer of its ascent, the mass of fuel ejected is small compared to the mass of the rocket. for this distance, which of the following indicates the changes, if any, in the kinetic energy of the rocket, the gravitational potential energy of the earth-rocket system, and the mechanicel energy of the earth-rocket system?
a. rocket kinetic energy-increasing system gravitational potential energy-increasing system mechanical energy-constant
b. rocket kinetic energy-decreasing. system gravitational potential energy-increasing sysem mechanical energy-constant
c. rocket kinetic energy-increasing system gravitational potential energy-decreasing sysem mechanical energy-decreasing
d. rocket kineic energy-increasing system gravitational potential energy nreasing syste mechanical energy-increasing
