A Golf ball is designed to achieve speeds up to 100 mph.
While it's certainly possible with super human strength to hit it harder, you'd need to achieve 2.38 km/s or 5,324 mph (8,568 kph) for it to escape the Moons gravity.
Whilst possible in sci-fi magazines, a golf ball would just explode as soon as it was hit at those velocities.
The speed required to go against gravity depends on the force needed to overcome it. In general, you would need to travel at least the escape velocity, which is about 11.2 km/s on Earth, to go against gravity and leave the planet's gravitational pull. This speed varies depending on the celestial body you are considering.
As the moons gravity is comparatively weak the escape velocity from the moon is much lower. The speed of the gasses would exceed this velocity and therefore escape to space. There are of course other factors that effect these matters.
The escape velocity of Phobos is 11.4 m/s, and the escape velocity of Deimos is 5.5 m/s. These are the minimum velocities needed for an object to overcome the gravitational pull of the moons and escape into space.
Escape velocity for the moon is a little over 5000 miles per hour. For the earth it is about 25,000 miles per hour. So the moon requires a fifth of the energy required to escape the earth.
You would not be able to see the moons from the surface; Jupiter's atmosphere is too thick.
The moons surface is covered with regolith. There are 2 main kinds of surface; maria and highlands. There are lots of craters and dust. the moons sky is always black.it has no air or water
No moons in our solar system have moons of their own, but it's theoretically possible.

Metorites
Yes it is similar to the moons surface
The Moon's gravity causes the lack of atmosphere (any possible atmosphere evaporates out into space in a fairly short time); and the lack of atmosphere causes the extreme temperatures.
