Question

If the kinetic enegy is k and its mass reduced ro half then what its kinetic energy

Answer 1

Answer:

Translational kinetic energy of a body is equal to one-half the product of its mass, m, and the square of its velocity, v, or 1/2mv2. ... Relativistic kinetic energy is equal to the increase in the mass of a particle over that which it has at rest multiplied by the square of the speed of light.
