The kinetic energy of a 204 kg motorcycle moves with a velocity of 6 m/s is 3672 joules (3672=0.5*204*6^2). This problem can be solved using the formula of an object's kinetic energy which is the energy of a motion. The formula of an object's kinetic energy is stated as KE = 0.5*m*v^2 where KE is the objects' kinetic energy amount, m is the object's mass, and v is the object's velocity.
