A racing car has a mass of 1670 kg.
The acceleration of gravity is 9.8 m/s
What is its kinetic energy if it has a speed
of 120 km/h?
Answer in units of J
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:
= 926 KJoules (approximated value).
Please note that 120 Km/h are equivalent to 120/(3.6)=33.3 m/sec
