A snowmobile does 400J of work in towing a sled to the top of a hill. During th etrip up the hill, it took 50J to overcome the work of friction. What is the potential energy of the motionless sled at the top of the hill?

Well I know that the formula for potential energy is mass * 9.8 m/s sq. * height.

But I can't figure this out.

Help?!
