Oscar has a mass of 17.4 kg and is sliding down a mud bank into water. The length of the mud bank is 4.6 meters. The coefficient of kinetic friction between Oscar and the bank is 0.377. The angle the mud bank makes with reference to the horizontal is 25.2 degrees. A) Calculate Oscar's acceleration downhill. B) Starting from rest at the top of the mud bank, how long will it take Oscar to slide the length of the hill? C)Starting from rest from the top of the hill, what is Oscar's velocity as he hits the water?
