Final answer:
The net work required to accelerate the car from 20.0 m/s to 30.0 m/s is 5000 J. Option A is correct.
Step-by-step explanation:
To calculate the net work required to accelerate the car, we can use the work-energy principle, which states that the change in kinetic energy is equal to the net work done on an object. The change in kinetic energy (ΔKE) can be calculated as:
ΔKE = 1/2 * m * (vf^2 - vi^2)
Where m is the mass of the car, vf is the final velocity, and vi is the initial velocity.
Plugging in the values:
ΔKE = 1/2 * 1000 kg * (30.0 m/s)^2 - 1/2 * 1000 kg * (20.0 m/s)^2 = 5000 J
Therefore, the net work required to accelerate the car from 20.0 m/s to 30.0 m/s is 5000 J.
