Runaway ramps are necessary on roads with steep grades in the
event of vehicular brake failure. Road grading is denoted as a
percentage, such that the percentage equals rise over run times
100. In the image, the road has a 7% grade. This is the only
picture associated with this problem I understand it is a little
blurry but it was given blurry. The sign says "7%" and "use lower
gear" back sign is not important, please help if you can.
2. If the road is covered in ice (that is, ignore friction), and
a fully loaded semi-truck (3.600E4 kg) starts at the top of the
hill with zero speed and 112.3 m of elevation, calculate its speed
at the bottom of the hill in m/s?
3. Find the change in kinetic energy of truck?
4. Find the change in potential energy of the truck?
5. Find the change in total mechanical energy of this
system?
6. How much work is done by gravity on the truck?
