5. A 6 ft board with mass of 2 kg is horizontal and attached to a swivel on oneside,the other is allowed to fall from rest. (One side of the board will fallwhile the other stays fastened....)a. How long will it take for the board to reach vertical?b. What is the angular velocity of the center of the board when it reachesvertical?c. What is the linear velocity of the center of the board when it reachesvertical?

As one end of the board is fixed, and the other end is allowed to fall freely, the board swivels…
