A force acting on an object moving along the x axis is given by Fx = (14x – 3.0×2) N where x is in m. How much work is done by this force as the object moves from x = -1 m to x = +2 m?

Answer:
72J
Explanation:
distance moved is equal to 3m.then just substitute x with 3m.
Fx = (14(3) – 3.0(3)2)) N
Fx =(42-18)N
Fx =24N
W=Fx *S
W=24N*3m
W=72J
