Physics Boarding

So i was chillin with my boi shabba, when we were like yo lets go longboarding. So we grabbed our yatchs and headed to the local chapel hill. Now while pushing we can hit a speed (according to the speed gauges in the road) of about 15 miles per hour. Which is roughly 6.7056 meters per second. Which is relativly fast. Also, courtesy of the speed gauges, that at the end of the hill we hit speed of 33 miles per hour, which is roughly 14.75 meters per second. We were disapointed that we couldnt even hit the speed limit of 35 miles per hour, but whatevs. Using this information and the principle of conservation of energy, we can find out the hieght of chapel hill. So check this out, conservation of energy states that mgh= 1/2mv^2. Sooooooo if we plug in our values for velocity and gravity, mass becomes negligable, and we end up with a hieght of 11.1 meters. Now that seems short because i did not take in account the friction between the wheels and the pavement considering we haven't learned rolling friction. Not to mention the friction within the bearings oin the wheels themselves. So the hills A LOT taller as im sure many of you can attest to. I guess at those speeds Shabba and I best be careful.

The Danskster out.
