I am working on the following problem. Susan's 13.0 kg baby brother Paul sits on a mat. Susan pulls the mat across the floor using a rope that is angled 30 degrees above the floor. The tension is a constant 31.0 N and the coefficient of friction is 0.190 . Use work and energy to find Paul's speed after being pulled 2.60 m. So far I have set up my force diagram with my x-axis along the ground. I have normal force pointing up. weight pointing down. tension to the left. and force susan to the right. I'm really not too sure where to go from here though. Any thoughts?
