1. A 20 kg block is pulled horizontally with a force of 500 N along a horizontal surface. If the coefficient of kinetic friction between the block and the surface is -0.2, find the acceleration of the block. Note: Follow the force recipe, clearly drawing a free body diagram, choosing a coordinate system and apply Newton's 2nd law in the x and y direction.
