Answer:
Explanation:
The formula for kinetic energy Ke=1/2mv^2 where Ke is kinetic energy, m=mass, and v= velocity.
If the kinetic energy is increased that means that there must be an increase in mass or velocity. However, since the velocity is squared that means that velocity affects the kinetic energy of the object more than the mass does.
