B) A force of 90 N is used to pull a truck 200 m along a horizontal floor. Determine the work done and the increase in K. E if there is no energy loss due to friction. ?
Work done to pull a truck by applying a force of
Since, there is no loss of energy due to friction hence the total work done on the truck will be converted into Kinetic energy (K.E.) of truck. Hence change in K.E.
