Question
In the system shown in the figure, suppose the block has a mass of 2.9 , the spring has a force constant of 550 , and the coefficient of kinetic friction between the block and the floor is 0.14. 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.
In the system shown in the figure, suppose the block has a mass of 2.9 , the spring has a force constant of 550 , and the coefficient of kinetic friction between the block and the floor is 0.14. 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.Explanation / Answer
(a)
work by spring= - 1/2 Kx^2
x=0.02
W1 = -0.11 J
(b)
work by spring= - 1/2 Kx^2
x =0.02 m
W2 = - 0.11 J
