consider a .10kg block being pushed horizontally along a tablewith a force of .10N so that the block moves 2.0m at a constantspeed in the same direction it is pushed.
How much work is done by the pushing force?
How much work is done by the frictionalforce that resists the pushing?
How much work is done by the force ofgravity acting on the book?
How much work is done by the normal forceof the table pushing on the book?
