The work done by the force Fs is given by:

$\overline{){\mathbf{W}}{\mathbf{=}}{\mathbf{F}}{\mathbf{\xb7}}{\mathbf{s}}}$

The work is done when accelerating an object from rest to a final velocity, v_{f} using a constant force, F.

The force causes acceleration. According to Newton's second law, F = ma.

What can be said about the work done by force Fs?

(a) It is Positive

(b) It Is Negative.

(c) It Is Zero.

(d) There Is Not Enough Information To
