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?
a. 13500 W
c. 23000 W
d. 27000 W
Average power = work/time
work = force(x) where x is magnitude of displacement.
force= mass x acceleration
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...
