A 1000 kg car, starting from rest, accelerates uniformly to 15 m/s in ten seconds. Assume air resistance is constant at 300N. What is the average power delivered by the engine?

Answers

a. 13500 W

b.18000 W

c. 23000 W

d. 27000 W

2. Relevant equations

Average power = work/time

work = force(x) where x is magnitude of displacement.

force= mass x acceleration

3. The attempt at a solution

the force is equal to 1000 kg x 15 m/s = 15000

I don't know how to factor in air resistance, or arrive at a final answer. The answer is A...
