Answer :
Final answer:
The term '4 g' refers to an acceleration four times the force of gravity, which is 9.8 m/s². Multiplying 4 by 9.8, we get 39.2 m/s², which is the maximum acceleration on a roller coaster.
Explanation:
In Physics, the 'g' in '4 g' stands for gravity, specifically, the force of gravity here on Earth. By standard, the force of gravity is equivalent to an acceleration of 9.8 m/s². When we say riders experience a force of up to 4 g, we mean they experience an acceleration four times as much as that due to gravity.
So, to find the equivalent acceleration of 4 g, we simply multiply 4 by 9.8 m/s². This gives us 39.2 m/s². So, the correct answer to your question would be B. 39.2 m/s².
