Physics question?

You are pulling your sister on a sled to the top of a 24.0 m high, frictionless hill with a 10.0� incline. Your sister and the sled have a total m of 50.0 kg. You pull the sled, starting from rest, with a constant force of 127 N at an angle of 45.0� to the hill. If you pull from the bottom to the top, what will the speed of the sled be when you reach the top?
