A 50-kg wooden box is resting on flat ground. Assume the friction coefficient between the surface of the box and the ground are 0.4 for static friction and 0.3 for kinetic friction. Assume the acceleration due to gravity is 9.8 m/s^2 and take right as the positive direction and left as the negative. 1.What is the friction force acting on the box?
2.If you push the box with 170 N to the left, what is the friction force acting on the box?
