Question

Gravity on the Moon is much weaker than on Earth. The expression below can be used to approximate the time in seconds it takes for an object to reach the surface of the Moon, when dropped from a height of h meters. To the nearest hundredth of a second, how long would it take for an object dropped from a height of 50 meters to land on the Moon? (Enter only the number, such as 3.25 without units.) √h/0.82

Answer 1

It will take an object dropped from a height of 50 meters √50/0.82 = 8.62 seconds to land on the moon.
