A wheel whose radius is 1.5 was rolling without slipping along a horizontal surface. At a certain instant, the angular velocity of the wheel was 2.5 rad per sec. counterclockwise and the angular acceleration was 3 rad per sec per sec clockwise. At the instant specified the magnitude of the vertical component of the linear acceleration of the particle at the point B was A. 4.50 fps per sec. C. 7.50 fps per sec. B. 5.50 fps per sec. D. 9.0 fps per sec.
