Start and First Hill
1. Calculate the potential energy at point C.
2. How much kinetic energy is needed at point B to reach the top?
3. What must the coaster’s speed be at point B to possess this kinetic energy?
4. If the coaster moves from AÆ B in 8 seconds, what is the rate of acceleration of the coaster?
4a. How much net force is required to produce this acceleration?
4b. If the coaster encounters 300N of frictional force, determine the force applied by the propulsion system.
4c. Complete the freebody diagram below

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
