Determine the power (in kW) required for a 1150-kg car to climb a 101-m-long uphill road with a slope of 30° (from horizontal) in 11 seconds : (a) at a

constant velocity, (b) from rest to a final velocity of 31 m/s, and (c) from 36 m/s to a final velocity of 6 m/s. Disregard friction, air drag, and rolling resistance.
