Time Left:1:19:11 Zora Ayasi: Attempt 1 Fred is pulling a stack of boxes on a toboggan through the snow. The total mass of the sled, with the boxes on it, is 60 kg. Fred pulls the toboggan in such a way that part of his applied force is to the right and part of his applied force is upwards, as shown in the diagram below. FN FFred(vertical) = 188 N rope Fred is pulling with FFred(horizontal) = 252 N The coefficient of kinetic friction between the snow and the toboggan is 0.18. Find (6 marks): a ) The normal force of the ground on the toboggan. b) The net force acting on the toboggan. C) The acceleration of the toboggan
