Question 17
17) The moment of Inertia of a solid uniform sphere of mass m and radius R is
given by the equation 1 = (2/5) mR². Such a sphere is released from rest at the top
of an inclined plane of height h= 10 m, length L, and the incline angle. If the
sphere rolls without slipping, find the linear speed at the bottom of the incline.
18) An object spins with angular velocity 10 rad/s. If the objects moment of
Inertia increases by a factor of 2 without the application of an external torque,
what will be the object's new angular velocity?
