**DISCUSSION THREAD**

Ask your questions here. Or, if you can help someone by answering their questions, then do that here. You can learn either way.

* DISCUSSION*This is a standard relative motion type of question. You are given complete information on the velocity vectors for A and P (both

*x*- and

*y*-components). And, you are asked to find the velocity of P with respect to A.

To do so, use the basic equation for relative velocity between two points: * v_{P/A} = v_{P} - v_{A}*. From this result, you are then asked to find the angle of the observed velocity of P, with this last step being just trig.
