Jan 16, 2012 · where is the normal force between the block and the inclined plane, is the mass of the block, and is the acceleration due to gravity. acts inward on the inclined plane and outward on the block. KEY FORCE CONCEPT (ACTION-REACTION) : Just because two forces are equal in magnitude and opposite in direction does not imply that they form an action ...
Two blocks, A and B, are being pulled to the right along a horizontal surface by a horizontal 100-N pull, as shown in the figure. Both of them are moving together at a constant velocity of 2.0 m/s to the right, and both weigh the same.

A block with mass m = 5.00 kg slides down a surface inclined 36.9 ∘ to the horizontal (the figure (Figure 1)). 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 6.25 kg and moment of inertia 0.500 kg⋅m2 with respect to the axis of rotation.
