QUESTION 9 A dog (of mass 50 kg) is happily sliding down a hill that has a coefficient of kinetic friction of 0.2. The hill has a slope of 20 degrees. Assuming that the dog is letting gravity do all the work, what is the magnitude of the dog's acceleration down the slope? 2.51 0.51 1.51 3.51 CS Scanned with CamScanner
