3. A disc is rotating about point O at 1 rad/s ccw, shown below. An ant and a beetle arelocated at points A & B, respectively. Both are walking straight

towards the center of thedisc, with the ant moving 20 mm/s and the beetle moving 10 mm/s, relative to the disc. (A) (12 points) Determine and draw the absolute velocity vectors of the ant and the beetlewith respect to the ground. Report the magnitude and direction of each vector. (B) (12 points) Determine and draw the velocity vector of the beetle with respect to theant. (In other words, the velocity of the beetle as observed by the ant.) Report themagnitude and direction this vector. Point B is 30 mm from the center. Point A is 60 mm from the center.
