3. A 100 kg roller coaster comes over the first hill at 2 m/sec (v o). The height of the first hill (h) is 20 meters. See roller diagram below. 1) Find the total energy for the roller coaster at the initial point. 2) Find the potential energy at point A using the PE formula. 3) Use the conservation of energy to find the kinetic energy (KE) at ...
c. At Great America, a roller coaster car is lifted to the peak of the first hill on the Shock Wave. d. A catcher puts out his mitt and catches the baseball. e. A falling parachutist opens the chute and slows down. 7. Before beginning its initial descent, a roller coaster car is always pulled up the first hill to a high initial height.

In this problem, you are first asked to find a speed of a roller-coaster when you are given information about how its height changes. If non-conservative forces are either known or small and if energy is converted from one form to another between the locations, then any time you relate speed and position of an object at two different points conservation of energy is the most direct way to ...
