1. A person uses a cable to try to start a 7 kg block, initially at rest, moving up a 25 incline. The coefficient of static friction between the block and the incline is 0.6, the coefficient of kinetic friction is 0.4, and the cable makes a 140 Angle to the incline, as shown. a) If the tension in the cable is 60N, will the block start to move? You must show a LARGE, very neat FBD to get credit, and you must fully justify your conclusion. Your FBD does not need three-word descriptions of forces, but it should include all other elements of a complete FBD. Hint: Don't rush or crowd your work, and use axes that are parallel- to and perpendicular-to the incline. b) Once you reach your conclusion, be sure to go back and finish your FBD with the block either at rest if it did not slip, or while it is moving if it did slip. 14 degrees 7 kg 25 degrees
