As illustrated in the right figure, three blocks with masses of mA, mB, and mC are placed on top of each other. On the middle block B, a force F is applied. Assume the static friction coefficient between the blocks is s and the kinetic friction coefficient between block C and the surface is k. Fill in the blanks with your answers in mA, mB, mC, F, s, k, and/or g. (Not all of the variables may be required.) (1) (a) What is the frictional force between blocks A and B if all three blocks move at the same speed v when the force F is applied? (b) If you want to be more formal What is the frictional force between the surface and block C, continuing from part (a)? Assume the surface is frictionless and the three blocks continue to move in unison. (b) What is the rate of change?
