6. Intro to Forces (Dynamics) / Forces in Connected Systems of Objects / Problem 1

A block weighing 1.5 kg is placed on another block weighing 2.5 kg. The blocks are tied as shown in the figure. The tension force in the lower rope is 25 N and μk = 0.35 for both the surfaces of the lower block which are in contact. Determine the tensile force in the upper rope.


Diagram showing two blocks, 1.5 kg on top of 2.5 kg, with a tension force of 25 N indicated.
