Question

A 351 kg box is pulled 9.00 m up a 30° frictionless, inclined plane by an external force of 5425 N that acts parallel to the

Answer 1

Answer #1

Draw the figure as follows: . 9 m F30 mg The work done by the external force is given by, W = Fs cose = mgs cose = (351 kg) (

> The first answer is incorrect because the formula for it would be 𝑊=[𝐹cos(𝜃)]𝑑. The answer for this first part would be 48825 N.
