An argon atom has a mass of 6.64 x 10kg has 5.5 x 108J of kinetic energy. At what velocity is it moving.?

  • Mechanics_physics -

    Use the definition of kinetic energy and solve for V.

    K.E. = (1/2) M V^2

    You'd better correct your mass M of the argon atom before you do the calculation. You left out an exponent.

    I suspect your kinetic energy exponent has a minus sign left out. Otherwise you would have to have a velocity close to the speed of light.
