A block of mass 5kg slides down a surface inclined at 30 degrees to the horizontal. The coefficent of
kinetic friction is 0.3. A string attached to the block is wrapped around a flywheel on a fixed axis at O.
The flywheel has a mass 30kg and a moment of inertia 0.25kg·m2 with respect to the axis of rotation. The
string pulls without slipping at a perpendicular distance of 0.4m from the axis. (a) What is the acceleration
of the block down the plant? (b) What is the tension in the string?
