Two dogs fight over a bone. The larger of the two pulls on the bone to the right with a force of 42 Newton. The smaller one pulls to the left with a force of 35 Newton.
a. Draw the free-body diagram for the bone.
b. Find the net force acting on the bone?
c. If the bone has a mass of 2.5 kilogram, determine what is its acceleration?
