Final answer:
The kinetic energy of the automobile is 3440625 joules (J).
Step-by-step explanation:
The kinetic energy of an object can be calculated using the equation:
Kinetic Energy (KE) = (1/2) mass x velocity^2
Using this equation, we can calculate the kinetic energy of the automobile given its mass of 1220 kg and velocity of 75 m/s:
KE = (1/2) x 1220 kg x (75 m/s)^2
Simplifying the equation gives:
KE = 0.5 x 1220 kg x 5625 m^2/s^2
KE = 3440625 J
Therefore, the kinetic energy of the automobile is 3440625 joules (J).
