A10.2 Continuation of A9.3. ACCELERATION DIFFERENCES. A toy boat is moving in a pool with the velocity and acceleration indicated below. An ant is on the corner of a rotating square plate, which pivots about a fixed point in the pool. The plate is 55 cm on each side and is rotating 0.5 rad/s ccw. The plate is also accelerating at 1 rad/s² ccw. In this problem, you will report the boat's observation of how fast the ant appears to be accelerating.
(A) Assume the ant has not yet started walking. Determine and draw the acceleration difference vector of the ant with respect to the boat, Ap4B2. Report the magnitude and direction of this vector.
(B) Assume the ant has been walking straight along the edge, with the velocity and acceleration indicated below. Building off of part (A), determine and draw the acceleration difference vector of the ant with respect to boat, A'D4B2: (This can easily be done on the same diagram from part (A).) Report the magnitude and direction of this vector.
