A uniform horizontal rod of mm 1.3 kg and length 1.3 m is free to pivot about one end as shown. The moment of inertia of the rod about an axis perpendicular to the rod and through the center of mass is given by If a 5.6 N force at an angle of 69 to the hor- izontal acts on the rod as shown, what is the magnitude of the resulting angular accelera- tion about the pivot point? The acceleration of gravity is 9.8 m/s2 . Answer in units of rad/s2. Answer in units of rad/3'2 Consider four round bodies of the same mass 9.4 kg and the same radius 0.13 m but of different geometries - a solid sphere, a spher- ical shell, a. solid cylinder, and a cylindrical shell. All four bodies start with zero initial velocity at the same distance from the bottom of the incline and roll without slipping down the same inclined plane. Which body reaches the bottom rst
