2. A 15. kg weight (m) is moving at a constant speed of 0.60 m/s up a ramp as it is pulled by a
pulley and weight system. The tension force is 55 N. Assume there is no friction. Draw a force
diagram in the space provided for the weight my. Include component forces and angles. Properly
label each of the forces and indicate which (if any) of the forces should be equal.
