4. (XX points) Along a 1-meter-dimeter circular dashed path on a plate, an ant is running with V = 100 mm/s and A = 250 mm/s2. The diameter of the

plate is 2 m. The plate i spinned at fixed point O and rotates with w =1 rad/s and a = 0.5 rad/s2 Draw and report the total acceleration vector of the ant with respect to the fixed ground. Use scratch paper as necessary.
