23. In the figure below, suppose that Barbara's velocity relative to Alex is a constant vBA = 52km/h and car P is moving in the negative direction of the x axis. Framed Frame B P WS Alex (frame A) and Barbara (frame B) watch car P, as both B and P move at different velocities along the common x axis of the two frames. The coordinate IPA= IPB + IBA in the A frame. (i) If Alex measures a constant vpA = - 78km/h for car P, what velocity vps will Barbara measure? (ii) If car P brakes to a stop relative to Alex (and thus relative to the ground) in time t = 10 s at constant acceleration, what is its acceleration apa relative to Alex? (iii) What is the acceleration apk of car P relative to Barbara during the braking?
