A body is moving along z-axis of a coordinate system under the effect of a constant force F= (2veci+3hatj+vhatk)N. Find the work done by the force in moving the body a distance of 2 m along z-axis

A body is moving along z-axis of a coordinate system under the effect

1.	A body is moving along z-axis of a coordinate system under the effect of a constant force F= (2veci+3hatj+vhatk)N. Find the work done by the force in moving the body a distance of 2 m along z-axis
Answer» ANSWER :`VECF=(2hati+3hatj+hatk)N,vecs=2hatk` `W=vecF.vecS=2J`
