Question

Toboggan Time! You and your friend have decided to take advantage of a late winter snowfall by taking a toboggan out to the Sugar Bowl. Let’s assume that the combined mass of the toboggan and its riders is 130 kg and the slope is angled upwards at 20.0° above the horizontal. a) Find the magnitude of the static frictional force if you remain stationary while on the slope. (4) b) What would be your acceleration down the slope if there is no friction? (2) c) If the coefficient of kinetic friction is 0.200, how long would it take to descend down the slope if the slope is 25.0 m long, assuming you start from rest? (4)
