The velocity of point P relative to frame A is vp/A = (-14.9 i + 19.4 J) ft/s and the acceleration of P relative to frame B is ap/B = ( 3.97i + 4.79j) ft/s/s Knowing that Frames A nd B do not move relative to one another determine the expressions for the velocity of P in frame B and the acceleration of P in frame A. Verify that the speed of P and the magnitude of P's acceleration are the same in the two frames.
