Ok, I am horrible at physics and I have a take home test and I need some help on some of the questions. So if you know how to do them pllease let me know and help me 1.)A 62 kg person is going down hill on a ski run angled at 37 degrees from the horizontal. The coefficient of kinetic friction between the skis and the snow is .15. How fast is the skier going at 5 seconds after starting from rest?
