2. The red block in the picture below weighs 11 kg and the blue block weighs 67 kg. The static coefficient of friction for the surface between the blocks is 0.60 and the blocks slide frictionlessly on the surface.

a) Assume that the force F is 300 N and that the block has an initial velocity of 5.0 m/s. How long does it take for the block to move 10.0 meters?

b) Plot all the forces acting on each of the two blocks.

c) Calculate the minimum force F that must be applied so that the blocks do not slide in the vertical direction.
