Thank you so very much
Let me see if I get this: KE=1/2(m)(v^2) but because I do not know the velocity, I would use the formula v=sqrt (2 g h) v=sqrt (2 g h) =sqrt (2*9.8*120) =sqrt (2352) then I would use the velocity 2352 for the formula KE=1/2(m)(v^2) =1/2 (3)(2352) KE= 3528
I am lost...please explain
