It has been a while, but I remember have trouble with this question. I ended up going to my professor, and he told me that a value had indeed been left out. So if I remember correctly, the height should be given as 10m. Hope that helps.
Whoops, I guess that doesn't actually answer your...
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...
Hi there, I'm studying for mechanics final and I came across a question I can't figure out how to do. The question is as follows:
A person is on a sled of mass 10 kg that’s moving to the right on a frictionless surface at 4 m/s. Just before the sled goes down a hill the person of mass 50 kg...
