Question: A 2-kg object is given a displacement s = (3 i + 3 j - 2 k) m along a straight line. During the displacement,

A 2-kg object is given a displacement Δs = (3 i + 3 j - 2 k) m along a straight line. During the displacement, a constant force F = (2 i - 1 j + 1 k) N acts on the object.

(a) Find the work done by F for this displacement.

(b) Find the component of F in the direction of the displacement.
