Thank you and thank you!

I'm just thinking that if the hill was a lot higher than it is, then the sled would have to travel a lot farther on the frictional surface in order to compress the spring the same amount. If they wanted the answer in terms of 'h' the height of the hill it would be no problem, but I'm pretty sure...
