Solve for kinetic energy. What is the equation linking kinetic energy mass and speed. Work and kinetic energy are.
In classical mechanics the kinetic energy of a non-rotating object of mass m traveling at a speed v is.
Equivalently the mass of a particle at rest is equal to its energy E divided by the speed of light squared c2. The formula for kinetic energy is KE. Equivalently the mass of a particle at rest is equal to its energy E divided by the speed of light squared c2. An object with less speed and more mass could potentially have the same Kinetic energy.
