A 4-kg block is connected by means of a massless rope to a 2-kg block in the figure. If the coeficient of sliding friction between the 4 kg mass and the table is 0.150, find the acceleration of the system, and the tention in the connecting cable.

Answer 1

I assume the 2kg block is over a pulley, hanging downward.

netforce=totalmass*a
2*g=(6g)a solve for acceleration a.

Tension=2(g-a)
