Block 1 (9 kg) is located on the surface of a table. A hand pushes horizontally to the right on block 1 with a normal force of 108 N. The coefficient of kinetic friction between the block and the surface equals 0.8. On a sheet of paper, draw the free body diagram for block 1 using the two-subscript notation from class. After completing the free body diagram, enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component. FORCES on BLOCK 1 Weight force on block 1 by Earth   W1E =  i +  j N  Normal force on block 1 by Surface   N1S =  i +  j N  Normal force on block 1 by Hand   N1H =  i +  j N  Frictional force on block 1 by Surface   f1S =  i +  j N  What is the acceleration a of block 1? a =  i +  j m/s2

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
