Analytical Physics 

1.  In the video they said that the top speed was 30 mph off of the full ramp. If we assume that immediately upon leaving the ramp his speed was completely horizontal and that he landed 72 feet away from the ramp, how high above the water (in meters) was the ramp's end? To receive credit, you must support your answer with physics. So, explain and show your work. 

2.  There are actually two inclines on this slide. However, to simplify this scenario, let’s assume the entire ramp was 165 feet long and at an angle of 24 degrees to the horizontal based on the incline of the slide and not the ramp up at the end. What speed (in meters per second) would you expect Adam to leave the ramp if there was no loss in energy? To receive credit, you must support your answer with physics. So, explain and show your work. 

3. If the speed you calculated in question 4 does not match 30 mph, calculate the loss in energy based on the speed you calculated and the actual speed with which Adam left the ramp. To receive credit, you must support your answer withphysics. So, explain and show your work. 

4. If the energy lost actually came from the constant frictional force between the person and  the ramp, estimate the coefficient of kinetic friction. To receive credit, you must support your answer with physics. So, explain and show your work.
