1. The problem statement, all variables and given/known data
A boy puts a 250kg elephant on a piece of carpeting and slides it across the floor by exerting a horizontal force of 425N on the elephant
2. Relevant equations
Ff = uKFn
3. The attempt at a solution
Fn = Fg
Fnet = Fap - Ff
Fnet = 425 - Ff
ma = 425 - uKFn
250a = 425 - uK(2450)
