a. A uniform solid ball has a few turns of light string wound around it. If the end of the string is held steady and the ball is allowed to fall under gravity, what is the acceleration of the center of the ball? (Assume the string remains vertical.)
b. Two people are holding the ends of a uniform plank of length 1 and mass in. Show that if one person suddenly lets go, the load supported by the other person suddenly drop from mg/2 to mg/4. Show also that the initial downward acceleration of the free end is 3/2g.
