Thewax has worn off, so there is now a nonzero coefficient of kineticfriction uk. The slope has just the right angle to make the tobogganslide with constant velocity. Find this angle in terms of w and uk.Example 5.17 Toboggan ride with friction IIThe same toboggan with the same coefficient of friction as inExample 5.16 accelerates down a steeper hill. Derive an expres-sion for the acceleration in terms of g, a, uk, and w.

A Smart Fortwo® car has a mass of 730 kg, which we assume on a flat surface is evenly distributed over its four tires. What is the maximum value of static friction on one tire if the coefficient of static friction between the tire and the road is 0.85? Note: In Iceland, though Smart cars are popular, there are special warnings about where to park them because the local winds can be strong enough to move the cars if they are not sheltered.
