Hi, I'm having trouble on a set of problems and I was wondering if someone could walk me through how to do one of these so I can at least attempt the rest. The problem says: "A point P moves uniformly along the circle x[squared] + y[squared]= r[squared] with constant agular velocity w. Find the x and y coordinates of P at time t given that the motion starts at time t=0 and [theta] = [theta]initial. Then find the velocity and acceleration of the projection of P onto the x axis and onto the y axis." I found the derivitive of the equation that was given but I have no idea where to go from there. Thank you for your help.
