Question

A constant force F = 3i + 1j- 2k moves an object along a straight line from point (0, -2, 9) to point (-10, 3, -1).

Find the work done if the distance is measured in meters and the magnitude of the force is measured in newtons

Answer 1

can someone answer this?

Answer 2

\[W=F\cdot d\]

Answer 3

add the i forces, the j forces, the k forces and square root all of them for the disctance
