Question

a child pulls a sled up a snow covered hill. the child does 600 j of work ok the sled. of the child walks 15 m up the hill, how large of a force must the child exert

Answer 1

To calculate the force exerted by the child, you need to divide the amount of work done (600 J) by the distance traveled (15 m).

force = work / distance

force = 600 J / 15 m

force = 40 N

So the child must exert a force of 40 Newtons to pull the sled up the hill.
