CONCEPT:

  • Kinetic energy: The energy needed to move the body of mass m from one point to another with stated velocity v is called kinetic energy.

The Kinetic energy is given as:

K.E = ½ × m V2

Where K.E = Kinetic Energy

m = mass of the object

V = Velocity of an object

CALCULATION:

Given that, m = 22 kg, v = 5 m/s

∴ K.E = ½ × 22 × 52

K.E = 275 J

Therefore, the kinetic energy of the object is 275 J
