A 9.30 kg block (m1) and a 11.85 kg block (m2) rest on a horizontal frictionless surface as shown below. The surface between the top and bottom blocks is roughened so that there is no slipping between the two blocks. A 30.7 N force is applied to the bottom block as suggested in the figure. Use the figure for the next 3 questions. ibb.co/ftFKB5C (the figure)
Calculate the acceleration for the two block system.
What is the force of static friction between the top and bottom blocks?
What is the minimum coefficient of static friction necessary to keep the top block from slipping on the bottom block?
