* Incorrect.
Car throwing stones. Chipsealing is a common and relatively inexpensive way to pave a road. A layer of hot tar is sprayed onto the
existing road surface and then stone chips are spread over the surface. A heavy roller then embeds the chips in the tar. Once the tar
cools, most of the stones are trapped. However, some loose stones are scattered over the surface. They eventually will be swept up by
a street cleaner, but if cars drive over the road before then, the rear tires on a leading car can launch stones backward toward a trailing
car (see the figure below). Assume that the stones are launched at speed vo= 11.2 m/s (25 mi/h), matching the speed of the cars. Also
assume that stones can leave the tires of the lead car at road level and at any angle and not be stopped by mud flaps or the underside of
the car. In terms of car lengths Lc=4.50 m, what is the least separation L between the cars such that stones will not hit the trailing car?

- Q20: Dr. Fahrrad has been riding his bike to his job and is curious how many ATP his body is breaking apart in order to do the work required to get to his job. Dr. Fahrrad rides 8.6 kilometers to his job, has a mass of 68.4 kilograms and has an average acceleration of 2.4 kilometers per second squared. The molecule ATP is able to do work, measured in kilojoules per mole of ATP broken into ADP. The SI unit for work is a joule. Using the information given we can calculate work and then convert to moles of ATP. The first step is to take stock of what we are given in the word problem and what we are trying to find. We have mass, distance, and average acceleration. We are trying to find how many ATP are required to power the bike ride to work. The equation for work, is force times distance and will tell us how many joules Dr. Farrhad is using on his bike ride. It also incorporates one of our given variables, distance.
