Hi guys i have a question on power and work i guess you gone help me out here is the question. 1.A 1170 kg car starts from rest and accelerates uniformly to 10 m/s in 16.1 s . Assume that air resistance remains constant at 302 N during this time.Find the average power developed by the engine. Answer in units of hp. here is what i did Power = work / time so average power = KE/t work = 1/2 . mv^2 work= 1/2 * 1170 * 10^2 = 29250 J so Power = W/t = 29250 J/ 16.1 = 3633.5403 w after that i changed watt to hp.
