Energy, work and power — practice question

The diagram illustrates the trajectory of a long-jumper. Point R, at which she lands, lies at the same horizontal height as point P, the point from which she leaves the ground. As the long-jumper runs and jumps, air resistance acts on her. Which graph indicates how the store of kinetic energy and the store of gravitational potential energy of the long-jumper change with time between points P and R?
