A 500N block is resting on an inclined plane and is subjected to a constant force of 600N acting parallel to the inclined plane. After the block has moved 3m from rest along the inclined plane, the force 600N is removed. The inclined plane has a slope of 3 vertical to 4 horizontal. Coefficient of friction is 0.20. Solve for the velocity of the block, in m/s, when the force 600N was removed. Round your answer to 2 decimal places.
