A motorcycle (mass of cycle plus rider = 2.5 102 kg) is traveling at a steady speed of 15 m/s. The force of air resistance acting on the cycle and rider is 1.5 102 N. Find the power necessary to sustain this speed under the following conditions. 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???
