Given that:
kinetic energy of an object (K.E) = ?
mass of the object (m) = 30 Kg ,
velocity of object (v) = 20 m/s,
We know that,
Kinetic energy is a form of energy, that an object as by reason of its motion.
mathematically,
The kinetic energy of the object (K.E) = 1/2 . (m. v²)
= 1/2.(30 × 20²)
= 6000 Joules
K.E = 6000 J or 6 KJ
The kinetic energy of the object is 6000 Joules
Units ; N.m = J (energy measured in Joules)
KN.m = KJ
