A bicyclist coasts down a 7.0 degree hill at a steady speed of 5.0 m/s. Assuming a total mass of 75kg (bicycle plus rider), what must be the cyclist's power output to climb the same hill at the same speed?(adsbygoogle = window.adsbygoogle || []).push({});

I got 90N * 5.0 m/s = 450W but that is not the answer

The book says 9.0 * 10^2 W

i am sorry for the trouble because this question has already been asked.

please can somebody help me coz i didnt understand the one explained b4?
