When a pole vaulter reaches the top of her vault, how does our potential energy compared to her kinetic energy a kinetic energy is less than the potential energy be the kinetic energy is greater than the potential energy see the kinetic energy and potential energy or the same day they kinetic energy is twice the amount of potential energy
1 answer
When a pole vaulter reaches the top of her vault, her potential energy is at its maximum. At this point, her kinetic energy is zero because she has momentarily stopped moving. As she starts descending, her potential energy decreases while her kinetic energy increases. At the point of release, when she starts moving towards the ground, her potential energy is minimal or zero, while her kinetic energy is at its maximum. Therefore, at the top of her vault, the pole vaulter's potential energy is greater than her kinetic energy.
