I need to know how to cancel terms in the equation Ve = sqrt 2(6.6742 x 10^-11 N m^2 / kg^2 (12.1kg))/0.106780959m
Ve = sqrt 2(mu)/r
Where r is the distance from the denter of the object to be escaped from, and mu is the Gravitational Constant multiplied by the mass of the object to be escaped from.
The Attempt at a Solution
I really have no idea where to start...
