A car of weight W is on an inclined road that rises by 100 m over a distance if 1 k and applies a constant frictional force (W)/(20) on the car. While moving uphill on the road at a speed of 10 ms^(-1), the car needs power P. It it needs power (P)/(2) while moving downhill at speed upsilon then value of upsilon is:

1.	A car of weight W is on an inclined road that rises by 100 m over a distance if 1 k and applies a constant frictional force (W)/(20) on the car. While moving uphill on the road at a speed of 10 ms^(-1), the car needs power P. It it needs power (P)/(2) while moving downhill at speed upsilon then value of upsilon is:
Answer» `20MS^(-1)` `5 MS^(-1)` `15 ms^(-1)` `10MS^(-1)` ANSWER :C
