A car of weight W is on an inclined road that rises by 100 m over a distance of 1 Km and applies a constant frictional W on the car. While moving uphill on the road at 20 force a speed of 10 ms !, the car needs power P. If it needs while moving downhill at speed v then value of 2 power v is: (a) 20 ms (b) 5 ms (c) 15 ms- (d) 10 ms
