Question

a body is pulled along a horizontal plane by a constant force of 100N applied at an angle of 45° to the horizontal the frictional force between the body and the plane is 20N. Calculate the workdone in moving the body through a distance of 2m​

Answer 1

Answer:

101.4 J

Explanation:

Work = force × distance

W = (100 N sin 45° − 20 N) (2 m)

W = 101.4 J
