A 1430 kg car speeds up from rest to 14.0 m/s in 7.00 s. Ignoring friction, how much power did that require? (Unit = W)​

Final answer:

The power required to speed up the car is 20020 W.

Step-by-step explanation:

To calculate the amount of power required, you can use the formula:

Power = (1/2) × mass × velocity^2 / time

Given that the mass of the car is 1430 kg, the final velocity is 14.0 m/s, and the time is 7.00 s, you can substitute these values into the formula to find the power:

Power = (1/2) × 1430 kg × (14.0 m/s)^2 / 7.00 s

Calculating this expression gives you a power of 20020 W.
