Question

4. VELOCITY DIFFERENCES. A toy boat is moving in a pool with the velocity indicated below. An ant, A,is on the corner of a rotating square plate, which pivots about

a fixed point in the pool. The plate is85 cm on each side and is rotating 0.5 rad/s ccw. In this problem, you will report the boat's observationof how fast the ant appears to be moving (i.e. the apparent velocity). (A) (8 points) Assume the ant has not yet started walking. Determine and draw the velocity vector ofthe ant as observed by the boat, VAB: Report the magnitude and direction of this vector. (B) (8 points) Assume the ant starts walking straight along the edge, with the velocity indicated below.Building off of part (A), determine and draw the velocity vector of the ant as observed by the boat, V,(This can easily be done on the same diagram from part (A).) Report the magnitude and direction ofthis vector.AB.
