(a) The work done in moving the crate along the floor is 7,050 J.

(b) The work done in moving the crate vertically is 0 J.

Work done in moving the crate horizontally

W = Fdcosθ

where;

  • F is total force to be applied
  • d is displacement of the crate
  • θ is the horizontal angle = 0

W = (1100 + 310) x 5

W = 7,050 J

Work done in moving the crate vertically

W  = Fd cos(90)

W = 0

Thus, the work done in moving the crate along the floor is 7,050 J.

the work done in moving the crate vertically is 0 J.
