Physics problem

[mickeychief]

Can anyone tell me how to solve the below question?

A 9.0kg hanging weight is connected to a string over a pulley to a 5.0 kg block that is sliding on a flat table. If the coefficient of kinetic friction is 0.15 find the tension in the string.

Start by drawing free body diagrams for block, hanging mass, and pulley (ideal pulley just changes direction of the tension force in the rope though). Account for all forces...use Newton's third law to help you out. That way you'll be able to identify the specific force you are asked to solve for and how it relates to the others.
