A block with mass m = 5.00kg slides down a surface inclined 36.9 ? to the horizontal (the figure (Figure 1) ). The coefficient of kinetic friction is 0.27. A string attached to the block is wrapped around a flywheel on a fixed axis at O. The flywheel has mass 29.0kg and moment of inertia 0.500 kg?m2 with respect to the axis of rotation. The string pulls without slipping at a perpendicular distance of 0.400m from that axis.
1. What is the acceleration of the block down the plane?
2. What is the tension in the string?
