Find the average power developed by the engine

Reference no: EM13196869

A 1.50 103 kg car starts from rest and accelerates uniformly to 19.4 m/s in 12.7 s. Assume that air resistance remains constant at 400 N during this time.

(a) Find the average power developed by the engine.Your answer differs from the correct answer by 10% to 100%. W

(b) Find the instantaneous power output of the engine at t = 12.7 s, just before the car stops accelerating. W
i've tried this problem a couple of times, and i have one more chance to submit my answer please help me. it due by 9am today
