You pull horizontally on a block with a force of 100 N for a distance of 4.0 m. There is a frictional force of 20 N acting on the block.
a. Make a sketch showing all the forces acting on the block (horizontal and vertical).
b. What is the work done on the block by the pulling force?
c. What is the work done on the block by the frictional force?
d. What is the work done on the block by the gravitational force?
e. What is the work done on the block by the support force?
f. What is the total work done on the block?
