1. A rigid object with moment of inertia 0.4 kg mº is spinning with angular speed of 0.2 rad/s around a fixed axis. A constant torque of 0.6 Nm is applied that increases the rotation speed of the object (no other force is present). (i) Calculate the angular acceleration of the object. (ii) Calculate the angular speed of the object at t = 4 s. (iii) Calculate the angle spanned by the object from 0 s to 4 s.

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. In order to change the angular momentum of an object, it is necessary to apply O a a net force to the object. O b. a net torque to the object. O c. a centripetal acceleration to the object. O d, both a net force and a net torque to the object. 2. We have three vectors, labeled A, B, and C. A points due west, B points due north, and C points due east. We don't know their...
