Part E : Find the magnitude of the angular acceleration. Please and thank you. The seesaw is pivoted in the middle,...
Torque and Angular Acceleration Learning Goal: To understand and apply the formula τ= Iα to rigid objects rotating about a fixed axis. To find the acceleration a of a particle of mass m, we use Newton's second law. Fnet =ma, where Fnet is the net force acting on the particle. To find the angular acceleration a of a rigid object rotating about a fixed axis, we can use a similar formula: Tnet = Ia, where Tnet=∑T is the net torque acting on the object...

1) Consider a system consisting of your instructor sitting on a stool while holding weights in his hands. The stool can spin; it rotates at a rate of 26 RPM. The instructor holds masses in each hand. When his arms are fully extended, the total rotational inertia of the system is 4.5 kg · m2. He then moves his arms close to his body, reducing the total rotational inertia to 1.5 kg · m2. If there are no external torques,...
