Questions For all the problems consider 9 = 9.8 m/s2. 1. A block whose mass is 6.0 kg sits on a level floor. The coefficient of static friction between the block and the floor is 0.42. What horizontal force is required to make the block move? Include a free body diagram in your answer. (5 marks) 2. A mass of 30.0 kg is hauled upward by a rope. The tension in the rope is 360 N. What is the magnitude of the acceleration of the mass? Include a free body diagram in your answer. (6 marks) 3. Consider the same system of blocks from the Forces Assessment (shown below). In this case, assume no friction is present between the 5.00 kg block and tabletop. (15 marks total) a. Draw a free body diagram for each block, and label all the forces. (2 marks - 1 mark/FBD) b. Write a second law equation for each block. (2 marks - 1 mark/equation) c. Find the acceleration (magnitude and direction) for each block. (8 marks) d. Find the tension in the rope
