Question 03- (a) A uniform density, solid sphere has a moment of inertia Isphere MR about its center of mass. If it were instead rotated about an axis tangent to its surface, what is the moment of inertia of the sphere about this axis of rotation. Note that you do not have to integrate anything to answer this question! (5 points) (b) Let M-5.00-kg and R=2.00-m. If the sphere is rotated about the tangential axis from part (a) and it began with an earlier angular speed of w₁ = 0 rad/s, what constant torque, t, is required to achieve a later angular speed of w, 3.00 rad/s after At = 14.0-s has elapsed? (5 points) (c) How great of an angular position change has occurred during this 14.0-s time interval? (5 points) (d) if the rotational kinetic energy is defined as RKF=1, what is the change in rotational kinetic energy over this 14.0-s time interval? Note that you can answer this so long as you complete part (a) and read the rest of the parts above. (5 points) (e) How much time is required for the completion of the first rotation? How much time required for the completion of the second rotation? Comment on why credit. (5 points) they are the same or why they are different for full I on why the 2010
