A block of mass 1.0 kg sits on top of one of mass 2.0 kg as pictured. The blocks have a coefficient of kinetic friction µk = 0.35 between them. There is no friction between the 2.0 kg block and the surface beneath it. Find the acceleration of the 2.0 kg bock, and the strength of the tension in the rope connecting the two blocks. Treat the ropes as massless.

7) Solve for the required acceleration and tension.
8) Comment briefly on whether your result is reasonably believable. If it is – what sort of result
could be easily identified as not believable for this problem?
