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 (h = 50) to land on the Moon? (Enter only the number, such as 3.25 without units.)

Plug 50 instead of h in the formula , 
Which will be √50/0.82 = 8.62325... Since you need need it hundredth it will be 8.62

Got it ?
