-- Multiply each side of the formula by 2
-- Then divide each side by t
-- Then subtract V(i) from each side.
32 kg m/s would be the kinetic energy.
Answer:
Greatest gravitational energy is at "C".
The planet has to do work "against" the field to get to "C".
Also, if m v R (angular momentum) is constant then as R increases v must decrease for this term to be constant and KE = 1/2 M v^2 must decrease also to get to point C.
