A baseball placed on a tee was hit by a bat 40 cm from the bat’s axis of rotation. If the angular velocity of the bat was 90 rad/s at the instant contact, what was the linear velocity of the ball when the bat contacted the ball (Assume that the linear velocity of the ball is the same as the linear velocity of the bat at the point at which it is struck)? If the baseball was hit 1 m above the ground and at a 30̊ angle how high does it go from the ground, how long does the ball fly in air until it comes down to the ground? If there was a 10-m fence 100 m away from the ball was hit would the ball go over the fence?
