A block with mass m=5.00kg slides down a surface inclined 36.9° to the horizontal (see the figure). The coefficient of kinetic friction is 0.25. A string attached to the block is wrapped around a flywheel on a fixed axis at O. The flywheel has mass 25.0kg and moment of inertia 0.500kg-m² with respect to the axis of rotation. The string pulls without slipping at a perpendicular distance of 0.200m from the axis. How much time does it take for the block to increase its speed by 4m/s? 0 A. 1.5s B. 2.2s C. 2.7s D. 3.1s E. 3.6s 5.00 kg 36.9° 0-0-0
