We are going to calculate the amount of potential energy that the roller coaster has. Using PE = mgh, calculate the potential energy if the mass of the roller coaster is 1,650 kg and it is carrying six 100-kg people. The height of the roller coaster in step 1 is 13.1 meters. Remember g = 9.8 m / s 2. 2. Now find the step number where the box on the part is completely blue, which means that the total energy is completely kinetic. What step number is this? Calculate the kinetic energy of the roller coaster knowing the mass from question 1 and the speed is 16 m / s. Use the equation KE = 1⁄2 mv 2.

3. According to the law of conservation of energy, energy cannot be created or destroyed. Comparing your answers for the numbers 1 and

2, is energy being conserved? (It's okay if your numbers are a little off)

4. Explain why in step 4, there is both potential energy and kinetic energy. Why is there more potential energy than kinetic energy in this step?

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
