Answer 2

Answer:

The kinetic energy of an object of mass 1 kg moving with a speed of 1 m/s​ is 0.5 J.

Explanation:

Kinetic energy is a kind of mechanical energy possessed by an object due to its motion. It is derived as half the product of mass and square of the velocity of the object. ie;

                                  K.E = (mv²)/2

We have mass, m = 1 Kg

            velocity,v  = 1 m/s

∴ K.E = (1 × 1²) / 2

        = 1/2

 K.E = 0.5 J
