In the system shown, suppose the block has a mass of 2.7kg, the spring has a force constant of 480 N/m, and the coefficient of kinetic friction between the block and the floor is 0.16. a) Find the work done on the block by the spring and by friction as the block is moved from point A to point B along path 2. B) Find the work done on the block by the spring and by friction if the block is moved directly from point A to point B.

Question
In the system shown, suppose the block has a mass of 2.7kg, the spring has a force constant of 480 N/m, and the
coefficient of kinetic friction between the block and the floor is 0.16. a) Find the work done on the block by the spring and
by friction as the block is moved from point A to point B along path 2. B) Find the work done on the block by the spring
and by friction if the block is moved directly from point A to point B.
