A car is accelerated from velocity v1 to v2 in the time period of t . The mass of the car is m. The inclined angle of the hill is a. The distance travelled along the hill is L. The vertical distance travelled is H. If v1= 5.00 m/s, v2 = 20.00 m/s, t = 2.00 s, m= 2500.00 kg, = 60.00 , L = 100.00 m, calculate the extra power, W= W H
