Question

the acceleration due to gravity on the Moon is about one sixth what it is on Earth. If an object is thrown upward on the Moon, how many times higher will it go than it would on Earth, assuming the same initial velocity? Okay, so I know that gM=1/6gE, and otherwise I am lost from there :/

Answer 1

@rajathsbhat , i tried working it out using \[{v}^{2}=v _{i}^{2}+2as\] but it gave me 3x higher and that is wrong. I rearranged the equation to solve for s and I put in a value for v^2-vi^2 and divided it by the g and by 1/6 and then divided my 1/6g answer by my g answer.

Answer 2

since g'= g/6 so new height h'= 6 times h

ans = 6 times
