E. O the work done is equal to the change in themechanical energy of the object.10. Intially an object has a potential energy of 20 Jand a kinetic energy of 150 J. Under the influenceof conservative and non-conservative forcesits potential energy changed to 40 J and its kineticenergy changed to 34 J. Calculate the net work done. (1 point)A. O-118 JB. 0-115 JC.
