80% of the kinetic energy is converted into potential energy, since the pole is only 80% effective.
What is potential and kinetic energy?
Potential energy is the energy that is stored in any object or system as a result of its position.
∵ P.E = m×g×h
The energy of a moving object or system is known as Kinetic energy.
∵ K.E = 1/2×mv²
The kinetic energy(KE) is changed into gravitational potential energy(PEG) when a pole vaulter reaches the top of her vault.
He ran, converting his kinetic energy to gravitational potential energy.
∴ PEG = 0.8×KE.
