A rocket with mass 5.00×103 kg is in a circular orbit of radius 7.30×106 m around the earth. The rocket's engines fire for a period of time to increase that radius to 8.70×106 m , with the orbit again circular. What is the change in the rocket's kinetic energy? Does the kinetic energy increase or decrease?
