1. A box sits at rest on a rough 40 incline

1. A box sits at rest on a rough 40 incline plane. It begins 60.ON to slide up the plane when the 70.0 N- pushing force 70.ON up the plane was applied. a. Draw the free-body diagram showing all the forces acting on the box. b. What is the coefficient of static friction? 40 2. Two boxes are connected by a lightweight cord and are resting on a table. The boxes have masses 12 kg and 10 kg. A horizontal force of 40 N is applied by a person to the 10 kg box as shown in the figure below. Draw FBD for each box. Find a. the acceleration of each box b. the tension in the cord m = = 12 kg my = 10 kg F : 40 N
