A 2.3 103 kg car starts from rest and accelerates along a horizontal roadway to +17 m/s in 21 s. Assume that air resistance remains constant at -500 N during this time. Find
(a) the average power developed by the engine and
(b) the instantaneous power developed at t = 15 s.
I am really confused about this. If you can help, I would appreciate it. Thanks!
