A boy pulls a sled with a force of 40N on a rope 2.5 meters long. The end that he holds is 1.5 meters higher than the end attached to the sled. What is the magnitude of the horizontal component that acts to pull the sled forward?

DrRuss,
If you draw a picture of this you will see that you have a right angled triangle 1.5 metres (vert) x 2.5 metres x 2.0 metres (horiz.). Note it is a 3,4,5 triangle, which should help for the next bit. Post your attempt and we can help further.
