Question

a stone is dropped from a certain height on earth and it takes 12 seconds to reach the ground. If the same stone is dropped from the same height on moon, find the time taken that it will take to reach the surface of moon. Ignore the air resistance. [ Given g moon = 1/6 g earth].​

Answer 1

Answer:

According to question

Time taken by stone at earth t = 12 sec

at earth a = g

So H = 1/2 g t^2

H = 5 * 12^2

At moon a = 6g

So H = 1/2 g/6 t^2

144 * 5 = 1/2 * 10/6 * t^2

Thus t = 29.39 Sec
