Taking the sum of forces in the y-direction:
T - Ff1 = 0
T1 = Ff1
But Ff1 = N1μk
The 10 kg block in the figure is tied to the wall with a rope. It sits on top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0 kg block is μk = 0.38.
Part A. What is the tension in the rope holding the 1.0 kg block to the wall?
Part B. What is the acceleration of the 2.0 kg block?
