A particle has a mass m and a velocity vxi + vyj + vzk. show answer No Attempt Which of the following is the correct expression for the kinetic energy of the particle? (1/2)m(vxi + vyj + vzk) (1/2)m(vx + vy + vz)2 (1/2)m(vx2 + vy2 + vz2) (1/2)m(vx2i + vy2j + vz2k)

less than one you can't create energy
