A car (m = 670.0 kg) accelerates uniformly from rest up an inclined road which rises uniformly, to a height, h = 35.0 m. Find the average power the engine must deliver to reach a speed of 23.9 m/s at the top of the hill in 22.7 s(NEGLECT frictional losses: air and rolling, ...)

  • Physics - ,

    gain in energy = (1/2) m v^2 + m g h

    power = gain in energy/22.7 seconds
