30 A lady runs up a flight of stairs. She accelerates in the first 4 steps, then decelerates in the last 3 steps. Eventually she is at rest at the top. From the second to the third step, what is the status of both kinetic and potential energy? (I think the height is increasing so is the acceleration. So I think both will increase but again total energy is always constant. pls explain)
