The passengers in a roller coaster feel 42 % heavier than their true weight as the car goes through a loop with a 30 m radius of curvature. What is the car's speed at the bottom of the loop? Use g = 10 N/kg.

Question
The passengers in a roller coaster feel 42 % heavier than their true weight as the car goes through a loop with a 30 m radius of curvature. What is the car's speed at the bottom of the loop? Use g = 10 N/kg. Hint: How heavy some one feels is another name for normal force. The problem therefore tells you the normal force. If you know weight and normal force, you can determine centripetal acceleration. You can substitute a value for mass if you wish.
