b) the road is sloped upward at 27° with respect to the horizontal

m = 250

v = 15

t = 90

distance = 1350

angle = 27 degree

The force of air resistance acting on the cycle and rider = 150

P = ?

( I FOUND THE TIME AND DISTANCE ,IM POSITIVE THE VALUES ARE CORRECT SINCE I SOLVED ANOTHER PART OF THIS QUESTION WITH THE SAME VALUES)

**I used the Formula of Power = Work/time

Power = 150*1350* cos 27 / 90 which comes out to be 2004.76

marked wrong . any suggestions???
