Calculate the net torque about this axis due to the three forces shown in the figure if the magnitudes of the forces are F1 = 27.0 N, F2 = 16.7 N, and F3 = 14.9 N. The plate and all forces are in the plane of the page. Take positive torques to be counterclockwise.

Computation. A uniform solid sphere has mass M = 8.9 kg and radius R = 0.2 m. What is its moment of inertia about an axis tangent to its surface? I- 2 kg .m² Record your your numerical answer below, assuming three significant figures. Remember to include a as necessary.

Baby Huey rolls a hollow sphere of mass M and radius R up a hillside, giving it an initial kinetic energy of Ki.  It rolls over the top of the hill of height h and keeps going.  The ball rolls without slipping the whole way, but it loses Wnc due to non-conservative forces between the foot of the hill and the top. a.  If M = 6.82 kg and R = 10.9 cm, find its rotational inertia. b.  Find the translational velocity at the top of the hill.
