Answer:
K.E on earth: K.E on moon= 1:6
Explanation:
we know that, weight=mass× acceleration due to gravity
denoted as, w=mg
W on earth = mg
=> m = W/g
w on moon = mg/6
=> m = 6W/g
we know that kinetic energy= 1/2 × mass × velocity²
denoted as, KE= mv²/2
kE on earth = mv²/2
=> Wv²/2g
KE on moon = mv²/2
=> 6Wv²/2g
Ratio of the KE on earth and KE on moon = Wv²/2g : 6Wv²/2g
=> Wv²/2g × 2g/6Wv²
=>1/6 = 1:6
