Welcome to PF Jacobojao!

Start with Newton's second law of motion. The block is moving at a constant velocity. What does that mean about its acceleration? What does that mean about the sum of forces on it (i.e. the net force on it)?

EDIT: The above was step 1. Step 0 should be (always!) to draw a free body diagram of the block, which will help you take an inventory of all the forces acting on it.
