Problem 82

A bicyclist of mass 75 kg (including the bicycle) can coastdown a 4.0 hill at a steady speed of 12 km/h. Pumping hard,the cyclist can descend the hill at a speed of 32 km/h. Usingthe same power, at what speed can the cyclist climb the samehill? Assume the force of friction is proportional to thesquare of the speed v; that is, Ffr = bv2, where b is a constant.

Step-by-Step Solution:
Step 1 of 3

Motions of the Stars and Sun 1. Constellations and Asterisms a. Constellations: one of 88 sections in the sky i. All countries agree on these regions ii. Utility of these regions is that if there is a particular object, you can get a rough idea of where it is in the sky based on what region it is in b. Asterisms: 2. using asterisms to navigate the sky a. Polaris is the most important star (North Star) b. It is very close to the spin axis, so it doesn’t look like it moves, so people use it as a reference point c. Some other famous constellations are the Big Dipper, the small dipper (the North Star is part of this)
