ANSWER
3030017.9 J
EXPLANATION
Kinetic energy is the energy of an object due to its motion - not its position. It is given by the equation,
[tex]KE=\frac{1}{2}\cdot m\cdot v^2[/tex]In this case, the mass of the race car is 731.8 kg, and its velocity is 91 m/s, so its kinetic energy is,
[tex]KE=\frac{1}{2}\cdot731.8kg\cdot(91m/s)^2=3030017.9J[/tex]Hence, the kinetic energy of the race car is 3030017.9 Joules.
