This is what I did:

Ep=50kg x 9.8m/s^2 x 2m/s = 980 Joules.

What do I do next?

**bobpursley**, Friday, October 14, 2011 at 10:10pmKE is 1/2 m v^2 Where is your 1/2 ? Why do you have g in the equation? Now point of fact,your mass is 50 kg, that is NOT what one "weighs".

**Anonymous**, Friday, October 14, 2011 at 10:29pmWait so I'm confused, the formula for KE is Ek=1/2mv^2

So it would be Ek=1/2(50kg) x 2m/s

Then I convert kg to pounds. There are .454kg in 1 lb so 50(.454)=22.7lbs

Ek=1/2(22.7lbs)(2m/s) = 22.7

Then what??
