2. Another bright physics student has decided to see if he can pull the ice cream freezer out of the cafeteria into the freshman hallway. He pulls the freezer with 50.N of force and it travels with a constant velocity. The cart has a total mass of 250. kg. c. Identify all forces acting on the cart bag and draw a qualitative force diagram in the space on the right.
