Question

In the figure, three connected blocks are pulled to the right on a horizontal frictionless table by a force of magnitude T3 = 78.7 N. If m1 = 15.7 kg, m2 = 27.0 kg, and m3 = 39.9 kg, calculate the tension T2.

Step 2

Since there no motion taking place along vertical direction, the normal force N and the mg force will get neutralized for all the three blocks.

N = mg

Step 3

Since the resultant force along horizontal direction is not zero...
