## Grantham PHY220 Week 2 Assignment Problem 8

If a car is traveling at 50 m/s and then stops over 300 meters (while sliding), what is the coefficient of kinetic friction between the tires of the car and the road?

A powerful motorcycle can accelerate from rest to 26.8 m/s (100 km/h) in only 3.90 s. (a) What is its average acceleration? (b) How far does it travel in that time? SOLUTION: Part (a). The average acceleration of the motorcycle can be solved using the equation $latex \overline{a}=\frac{\Delta v}{\Delta t}&s=0&fg=000000$. Substitute the given into the equation. … Continue reading College Physics Problem 2.28
