Transcribed Image Text:

A rocket with mass 7.00x103 kg is in a circular orbit of radius 7.40x10° m around the earth. The rocket's engines fire for a period of time to increase that radius to 8.80x106 m, with the orbit again circular. Part A What is the change in the rocket's kinetic energy? Does the kinetic energy increase or decroase? Express your answer with the appropriate units. Enter positive value if the kinetic energy increases and negative value if the kinetic energy decreases. HẢ ? AK = Value Units Part B What is the change in the rocket's gravitational potential energy? Does the potential energy increase or decrease? Express your answer with the appropriate units. Enter positive value if the gravitational potential energy increases and negative value if the gravitational potential energy decreases. HA AU = Value Units Part C How much work is done by the rocket engines in changing the orbital radius? Express your answer with the appropriate units. HA ? W = Value Units A rocket with mass 7.00x103 kg is in a circular orbit of radius 7.40x10° m around the earth.
