Question

A force does 210 J of work when it acts on a moving object and its direction is in the same direction as the object’s displacement. How much work does this force do when the angle between it and the object’s displacement is 56°

Answer 1

Answer:

When the angle is 56° the work done is 117.43 J

Explanation:

Work = F . s = Fscosθ

We have

   W1 = 210 J, θ = 0°

Substituting

      210 = F x s x cos 0 = Fs

Now we have to find W2 when angle θ = 56°

Substituting

      W2 = F x s x cos 56 = 210 cos56= 117.43 J

When the angle is 56° the work done is 117.43 J
