A baseball is struck by a bat 46 cm away from the axis of rotation when the angular velocity of the bat is 70 rad/s. If the ball is hit at a height of 1.2 m at a 45° angle, will the ball clear a 1.2 m fence 110 m away (Assume that the initial linear velocity of the ball is the same as the linear velocity of the bat at the point at which it is struck.) (No, the ball will fall through a height of 1.2 m at a distance of 105.7 m.)
