1. A magazine reports that a new type of plastic ski is even more water repellent and that, on a gentle 203-m slope in the Alps, a skier reduced his time from 61 to 42 s with the new skis. Assuming a 3.0 degree slope, compute the coefficient of kinetic friction for each case. I am having trouble just starting the problem. The time is throwing me off. Idk what equations to apply to involve this. I'm not looking for the answer but if someone could point me in the right direction that would be very helpful! thank you.
