15. Two men are pushing on opposite sides of a box with a MASS of 30 kg. The man on the left is pushing with a force of 120 N, while the man on the right is pushing with a force of 80 N. The box is accelerating at a rate of 0.5
m/s/s from left to right. For this problem, we need to consider friction.
a. List all of the interactions and draw a free body diagram of all of the forces acting on the box.
b. Write your Net Force Equations.
c. Find the force due to friction acting on the box.
d. What is the size of the Normal force exerted on the box by the ground?
e. What is the coefficient of friction (u) between the box and the ground?
