Question

. An object reaches a maximum vertical height of 23.0m when thrown vertically upward on the earth. How high would it travel on the moon where the acceleration due to gravity is about one sixth that on the earth ? Assume that initial velocity is the same.
1) 138 m 2) 100m 3) 10 m 4) 69 m

Answer 1

We know hmax = u^2 / 2g
When gravity become - g/6
Then hmax = u^2 /(2g/6)
So itll be 23*6 = 138 m
