Unformatted text preview: conds. Give the angle measured counterclockwise from the positive x‐axis. (2 points) 8. Block A in the figure below weighs 2 N, and block B weighs 5 N. They are connected by a light, flexible cord passing around a fixed, frictionless pulley. The coefficient of kinetic friction between the two blocks is μ = 0.3 and there is no friction with the table. A force F is applied to block B to drag it to the left at constant speed. Take g = 10 m/s2. a) Draw a free body diagram for each box on the axes provided below, clearly indicating all the forces acting on the block. Label each force such that it can be easily identified. Make sure you use the same label for all action‐reaction pair of forces (10 points) Block A Block B y y x x b) Write Newton’s second law (on the x and y axis) for block A. Please use only algebraic symbols (no numbers!...
