A student is swinging a 1.55kg ball attached to a 0.5m long string in a vertical circle as shown (measured from the hand to the center of the ball). When the ball reaches the highest point the ball is traveling 3.9m/s. Neglect drag. number of forces in plane: centripetal force: Are all forces balanced? What is the centripetal acceleration of the ball? unit What is the centripetal net force on the ball? unit How much tension is in the string? unitA 60kg skateboarder (including the skateboard) is skating over a hill as shown. When the skateboarder reaches the peak of the hill, he has both feet on the board and is moving 8m/s.
