How much energy did the push give the cat? Do you know the equation for gravitational potential energy?

No, I"m not sure what the equation for gravitational potential energy is...

nevermind! I figured it out!

P.E. = 9.8(4.5)(.97) = 42.777J

42.777/.23 = 185.987W

& 746W = 1hp

185.987/746 = .249hp
