Please help me understand how to solve these? Please provide diagrams if possible.

5) Two baseballs are consecutively hit by a bat. The first ball is hit 0.2 m form the bat's axis of rotation, and the second ball is hit 0.4 m from the bat's axis of rotation. If the angular velocity of the bat was 1,719 degrees/s at the instant that both balls were contacted, what was the instantaneous linear velocity of the bat at the two contact points? (2 points) 6) During a windmill-style softball pitch the ball has an instantaneous angular acceleration of 6.5 rad/s2. If the distance from her shoulder joint to the ball is 0.7 m, what is the tangential acceleration of the ball? (1 point) 7) While completing a lateral raise exercise the lifter moves her arm at an angular velocity of 1.5 rad/s. If the distance from her shoulder joint to the dumbbell in her hand is .6 m, what is the centripetal acceleration of the dumbbell? (1 point) 8) A male hammer thrower spins with an angular velocity of 1200 deg/s. The hammer has a mass of 7.26 kg and the distance from his axis of rotation to the hammer head is 1.2 m. What is the linear velocity of the hammer head? What is the centripetal force in Newtons needed to spin the hammer at that velocity? (2 points)
