Please help me I am confused explain step by step A baseball sits on a tee-ball stand. A child hits it with a bat moving east at 6.0 m/s and the ball flies off at 15 m/s. Determine the speed and direction of the bat immediately after impact. Tee-ball equipment is smaller than regular baseball equipment. The ball weighs 0.125 kg and the bat 0.500 kg. (+2.25 m/s)
