### Question

Can you hit a golfball into orbit on the moon?

Asked by: Eric

### Answer

The escape velocity of an object from the surface of any planet, moon or star is:

V=((2*G*M)/R)^{(1/2)}

Where G is the universal gravitational constant, M is the mass, and R is the radius of
the planet, moon or star.

G=6.673 x 10^{-11}Nm/kg^{2}

Mass of the moon = 7.36 x 10^{22}kg

Mean radius of the moon = 1.74 x 10^{6}m

The escape velocity from the surface of the moon is approximately 2380 m/s.
In conclusion I think it is obvious to the most casual observer that it is not possible
for a human to drive a golf ball at these speeds. No, you cannot hit a golf ball into
orbit on the moon.
