Kinetic energy is calculated from the formula KE = (1/2)mv2. Suppose a mass of 14.2 kg (m = 14.2 kg) is moving with a velocity of 750. ms-1 (v = 750. meters per second). Calculate the kinetic energy of this mass in units of Joules.
What problem are you having? Isn't this a case of substituting and working the calculator?
