7. A child is pulling a 2.00 kg wooden toboggan across rough snow at a constant velocity. The rope pulls upward on the toboggan at an angle of 25 above the horizontal. Friction is not negligible. (a) Draw a completely labeled free body diagram of the toboggan, with axes and angles. (3) (b) Use Newton's Second Law to create equations for the horizontal and vertical directions. (3) (c) Find the magnitude of the tension force. (4)
