4) In order to determine the moment of inertia I of a rotating platform, a string is wrapped around a spool of radius 2.0 cm beneath the platform. The string is then fed over a pulley with a hanging mass attached to its end as shown in the diagram below. The hanging mass is then released from rest, and its linear acceleration is measured. m Rotation axis Base Rotating track Ball Launcher O a. Before collision D String If the hanging mass is M= 100 g, and its linear acceleration is a = 2.5 m/s², what is the moment of inertia I of the rotating platform? 5) Using the same rotating platform as in problem 4, a ball of mass m = 50 g is launched into the catcher on top of the platform as shown in the diagram below. After the ball is caught by the catcher, the angular velocity of the system is = 2.2 rad/s. Rotating track Base Catcher Smart pulley M Radius b. After collision If the catcher is R= 20 cm away from the axis of rotation of the platform, what is the linear velocity v of the ball before it is caught? 4) In order to determine the moment of inertia I of a rotating platform, a string is wrapped around a spool of radius 2.0 cm beneath the platform.
