Please note that the kinetic energy T of a particle whose mass is m, and whose speed is v, is given by the subsequent formula:

T= (1/2) m v^2, substituting your numerical data into the above formula, we get:

T= (1/2)*1670*(33.3)^2=

= 926 KJoules (approximated value).

Please note that 120 Km/h are equivalent to 120/(3.6)=33.3 m/sec
