Assuming elastics collision, we could use the law of momentum conservation to calculate the speed of black and projectile post-collision V:
mv = (M + m)V
This would make the system moves up, which convert its kinetic energy to potential energy. By the law of energy conservation when the mass reaches its highest point (aka speed = 0)
The moon surface is
visible to an observer on earth due to the gravitational force that attracts
the moon to the earth. The more massive the body is, the more the smaller body
is attracted to the larger body. We can only see the side of the moon due to
the speed at which the moon rotates.
