Since angular momentum is conserved, if the moment of inertia decreases, then the angular speed must increase (L=Iw) If the ball is initially moving at 2.8 m/s in a circle with a radius of 0.30 m, what will be its tangential speed if the string is pulled down to reduce the radius of the circle to 0.15 m? (neglect the mass of the string) (5.6 m/s)

OBJECTIVE: To determine experimentally the moment of inertia of an object and to compare this with the theoretical value obtained from the mass and dimensions of the object. THEORY: When an object at rest is set into rotation about some axis, it has a tendency to keep rotating at some angular speed…
