The roller coaster shown below starts from rest at the top of the 20.0 m hill. Work done by frictional forces is negligible. (a) Use the GFS method to show and explain each step of your work. (b) Draw a sketch of the roller-coaster ride and indicate the location of GZ. (c) Write the CMEP equation when the roller coaster is at the Start and Finish positions, and then simplify it using the Given. (d) What is the final speed of the roller coaster? (e) Rewrite the CMEP equation and determine the roller coaster's final speed (again assuming negligible friction) if its initial speed is 5.00 m/s. Homework Start Figure 7.8 V = 0 h = 25 m h = 20 m Finish V = ? The roller coaster shown below starts from rest at the top of the 20.0 m hill. Work done by frictional forces is negligible.
