Answer

25 Joules

Work Step by Step

To find how much greater the Kinetic Energy would be, we need to find the work done by the rope, Fr. Since W = Fd then we use Fr = 50N and d = .50m to find the work done, which is 25 Joules. If the rope were not there, the Kinetic Energy would have increased by this additional 25J.
