It depends on the angle of the earth, and our point of view. A full moon would occur if we were to be right in front of it.
Rate of change of momentum = impact force
(m*v-m*u)/t = F
4000*20/t = 80000 (note: v is zero as it stopped)
<span>soo, t = 1 sec</span>
Potential equals kenecric at the bottom so potential would also increas
