Final answer:
The kinetic energy of Darcy's car traveling at 19 m/s and weighing 23 kg is 218 J.
Step-by-step explanation:
The kinetic energy is given by the formula: KE = 0.5 * mass * velocity^2. In this case, the mass of the car is 23 kg and the velocity is 19 m/s. The calculation results in the kinetic energy of Darcy's car, reflecting the energy associated with its motion. The final numerical value represents the amount of work required to bring the car to rest, showcasing the dynamic aspect of its movement. Plugging these values into the formula, we get:
KE = 0.5 * 23 kg * (19 m/s)^2 = 218 J
Therefore, the correct option is A) 218 J.
