A constant force of 41.5 N,directed at 32.9  from horizontal,pulls a mass of 12.7 kg horizontally a distance of 3.33 m.Calculate the work done by the force.(in J).

Question

Quizplus · Accepted Answer

The work done by the force is calculated using the formula:
Work = Force x Distance x Cosine(angle)
where the angle is measured from horizontal, so in this case, the angle is 32.9 degrees.

Plugging in the given values:
Work = 41.5 N x 3.33 m x Cos(32.9°)

Using a calculator:
Work = 1.16 x 10^2 J

Therefore, the best choice is (D) 1.16 x 10^2 J.
