Test 2-PHY 251 001-Fall 2021 Name 4. (40 pts) Blocks A and Care attached to one another by a lightweight rope and the same for Block Bland C. Block A of mass 3.0 kg and Block B of mass 5.0 kg are on a flat surface with a static coefficient of friction of / =0.45 and a kinetic coefficient of friction of = 0.30. Assume 0= 60 and 4=15 and that the pulleys are frictionless and massless. a. (10 pts) Draw the free-body diagrams and label all the forces for each of the blocks A, B, and C. A b. (15 pts) What is the maximum mass that Block C can have In order to keep the system stationary? C. [15 pts) Assuming Block C is located 1.0 miabove the ground, what mass does Block Cineed to be in order for it to accelerate to the ground in 4.0 seconds
