Ablock is pulled along a horizontal surface at a constant speed by a force (14.1i 0 j 5.1k). the direction k is perpendicular to the surface. the block moves 6 m. how much work, in n m, does the force do?

Explanation:

given,

F = 14.1 i + 0 j + 5.1 k

displacement = 6 m

Assuming block is moving in x- direction

we know,

 dW = F dx

hence, work done by the force is equal to
