A leftward force is used to pull a large wagon up an incline at an angle of 55.6 degrees. In the wagon
there is
amn
unknown mass that makes it very difficult to move, but a force
applied can set the wagon into constant motion. Let the force applied to the wagon and its
unknown mass be 77.9 N. The coefficient of friction between the wagon's wheels and the
floor is 0.211. Determine the mass of the wagon if it was empty.
ii. Let's say that the unknown mass in the wagon is 95.5% * mass of the
wagon. What is the weight of the wagon when its empty and what is the
weight of the unknown mass, separate of the wagon?
