Question

a person jumps 5m on earth, how high will the person jump on moon

Answer 1

as gravity on the moon is one sixth of the Gravity on Earth so that the person jump 5 metres he will jump 30 metres up in the air in Moon

Answer 2

acceleration due to gravity on earth = g

acceleration due to gravity on moon = g/6

let the energy of man be E

on earth

E = mgh

on moon

E = mgH/6

the energy of the man is same

so

mgh = mgH/6
h = H/6
5 = H/6
H = 30 m
