What's the total mechanical energy of a 400kg satellite in circular orbit 1100km above Earth's surface?
The Gravitational potential energy U=-(Gm1m2)/r
kinetic energy k=1/2mv^2
The Attempt at a Solution
At first i thought i could do just the gravitational potential energy, then figured out i was missing the kinetic energy. But one problem, i can't remember how to find the velocity
Would it have anything with angular velocity with it?
So i have the gravitional potential energy, just not the kinetic enegry...
