The kinetic energy of a moving object is ke mv22 where m, Ask an Expert

Academics

The kinetic energy of a moving object is KE = (mv²)/2, where m is the mass and v is the speed. An average apple contains about 0.5 million joules of rest energy and has a mass of about 0.1 kg [E=mc²]. How fast must the apple travel to have kinetic energy equal to the rest energy it contains?
