Roller Coasters
The information on this diagram is to be used for the accompanying questions.
Using the information shown on
the diagram above, determine the answers to the following questions, given that
the mass of the car is 500 kg.
1. How fast is the car traveling at location B if it coasted down the
back side of the first hill? Note the velocity at the apex. (1
mark)
2. What is the normal force
exerted on the car as it enters the bottom of the first hill if its radius is
60.0 m at location B. (3 marks)
3. How fast is the car traveling
when it reaches the horizontally banked curve? (1 mark)
4. Given that the radius of the
horizontal banked curve is 70 m, at what angle to the horizontal should the
curve be banked for the velocity determined in #3 (neglect any frictional
forces)? (6 marks)
5. What is the velocity of the
car at the top and bottom of the looptheloop? (2 marks)
6. What is the normal force
exerted on the car at the top of the looptheloop? (3 marks)
