A rocket with mass $4\mathrm{.}00103$ kgkg is in a circular orbit of radius $7\mathrm{.}50106$

m around the earth. The rocket's engines fire for a period of time to increase that radius to $8\mathrm{.}90106$ m$,$ with the orbit again circular. What is the change in the rocket's kinetic energy? Does the kinetic energy increase or decrease?

Express your answer with the appropriate units. Enter positive value if the kinetic energy increases and negative value if the kinetic energy decreases.
