A child is tobogganing down a hillside. The child and the toboggan together have a mass of 50.0 kg. The slope is at an angle of 30.0 to the horizontal. Find the acceleration of the child a) in the case where there is no friction, b) if the coefficient of friction is 0.15. Assume that the positive y direction is pointing in the direction of the normal force. Assume that the positive x direction is down the incline. Be sure to draw the appropriate free body diagrams and demonstrate completely your solution to the problems. m = 50.0 kg 30.0
