A ball with a mass of 250 g is tied to a light string that has a length
of 2.40 m. The end of the string is tied to a hook, and the ball hangs motionless below the hook. Keeping the string taut, you move the ball back and up until it is a vertical distance of 1.16 m above its equilibrium point. You then release the ball from rest, and it oscillates back and forth, pendulum style. As usual, we will neglect air resistance. Use g = 9.80 m/s2.(a) What is the highest speed the ball achieves in its subsequent motion?
(b) What is the maximum height the ball reaches in its subsequent motion (measured from its equilibrium position)?
(c) When the ball passes through the equilibrium point for the first time, what is the magnitude of the tension in the string?
