A 25 newton force applied on an object moves it 50 meters. The angle between the force and displacement is 40.0°. What is the value of work being done on the object?

Respuesta :

The total work done is 957.56 joules. This is calculated as work is equal to 25N time 50 meters time cosine 40 degrees.

Answer:

Work being done on the object = 766.04J

Explanation:

Work done by a force  is calculated by finding dot product of force and displacement.

            W = F . s

             F = 25 N

              s = 50 m

               θ = 40.0°

W = F . s = Fs cosθ = 25 x 40 x cos 40 = 766.04J

Work being done on the object = 766.04J
