Homework Equations
Im at a chapter named Energy and its conservation so I am guessing i have to use these
PE=mgh
E= KE + PE
KE(before)+PE(before)=KE(after)+PE(after)
The Attempt at a Solution
I also tried some other equations such as
Velocity(final)^2= V(initial)^2 + 2a(d)
V(f)= 9^2 + 2(9.8(don't know if it would be gravity))(2.4)
(Please try to fix any wrong ideas that i have in my head)
