Question

A force of 375 N acts on an object to do 3.90 × 10³ J of work. If the magnitude of the displacement of the object is 18.6 m, then the angle between the force and the displacement is?

Answer 1

hope this helps you friend!

Explanation:

W=FScos∅              

(∅ is the angle between the force applied and the displacement)

hence

3.90*10³=375*18.6*cos∅

cos∅=3900/(375*18.6)=0.5591

hence we can either write

∅=cos⁻¹(0.5591)

or we can take approximately cos∅=0.5=1/2=cos 60
