A motorcycle (mass of cycle plus rider = 2.5 x 10^2 kg) is traveling at a steady speed of 20.0 m/s. The force of air resistance acting on the cycle and rider is 2.00 x 10^2 N. Find the power necessary to sustain this speed if the road is sloped UPWARD 37.0 degrees with respect to the horizontal. OK this is how im doing this problem (Check my work on here) First Step (finding net force): Fnet = Wsin37 + Fa (exerted) = (250)(9.8)sin37 + 200 = 1674 N (briefly, Just tell me if it's sin or cos here! -- main confusion) Second Step (finding power from givens): P = (Fcos37) V = (1674cos37) (20) = 2.67 x 10^4 W Again, Just check my work to see if i am doing it correctly. If not, then please give me a little help -- hint: im bad with conceptual understanding (try to help me visual what i did wrong!). Thanks and sorry if im asking for too much!
