1. Homework Statement

We're given a pulley with one side hanging (A) and the other on an inclined plane (B). We are also given that the mass of A is 15 kg and the mass of B is 17 kg. The angle of elevation of the inclined plane is 32 degrees. The problem asks us to find the frictional force on block B.

Homework Equations


Since ΣF = 0, we need to sum up the forces somehow. (because of constant velocity)

The Attempt at a Solution


I tried drawing force diagrams for both blocks, but I can't figure out how to incorporate tension into that.
