How to calculate percentage of its kinetic energy

Use the formula =1/2^2

KE = kinetic energy

m = mass of a body

v = velocity of a body

kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s^2.
