12. (15) A wheel starts from rest and rotates with constant angular acceteration to r angular speed of 11.4 rad/s in 2.96 s. a) Find the magnitude of the angular acceleration of the wheel. b) Find the angle in radians through which it rotates in this time interval. c) The diameter of this wheel is 30 cm. What linear distance does the wheel travel if t rols without slipping? xtra Credit: (3) I have a slender rod, mass ‘M’, length’L’. I want to spin it so that it has t mallest possible moment of inertia. Draw where the axis of rotation should be for the mallest moment of inertia.
