A force of 25 N acts on a body and produces a displacement of 5 m. Calculate the work done?

Open in App

Solution

Given:
Force is = 25 N
Displacement = 5 m
Calculation:
Work done is given as,
$W o r k d o n e (W) = F o r c e (F) \times D i s p l a c e m e n t (d) W o r k d o n e (W) = 25 N \times 5 m W o r k d o n e (W) = 125 J$
Hence, Work done (W) is 125 J.
