Ek = 1/2 m v²=1/2 x 2 x 10²=100 joule Ep = m x g x h=2x10x15=300 joule Em= Ek + Ep =100 + 300=400 joule

EK = 1/2 x m x vkuadrat = 1/2 x 2 x 10 x 10 = 1 x 10 x10 = 100 J EP = m x g x h = 2 x 10 x 15 = 20 x 10 x 15 = 300 J EM = EK + EP = 100 J + 300 J = 400 J
Ep = m x g x h=2x10x15=300 joule
Em= Ek + Ep =100 + 300=400 joule
= 1/2 x 2 x 10 x 10
= 1 x 10 x10
= 100 J
EP = m x g x h
= 2 x 10 x 15
= 20 x 10 x 15
= 300 J
EM = EK + EP
= 100 J + 300 J
= 400 J
