How to Determine the Speed of a Train Moving Around a Curve
What is the best way for Lillian to figure out how fast a train can move around a particular curve before it falls off the track?
A. Drive a train along a curve at different speeds until it falls off of the track.
B. Build a model train and track, and test one train going around one curve at different speeds.
C. Build a model train and track, and test one train going around several different curves at one speed.
D. Build a model train and track, and test different-sized trains going around one curve at the same speed.
Answer:
B. Build a model train and track, and test one train going around one curve at different speeds.
If Lillian wants to know how fast a train can move around a specific curve before it falls off the track, the best way for her to figure this out is by building a model train and track. By testing one train going around one curve at different speeds, she can gather valuable data and insights into the situation.
This approach allows Lillian to safely conduct experiments and analyze the train's behavior without putting anyone in danger. It also provides a controlled environment for her to observe the effects of speed on the train's stability around curves.
Building a model train and track is a practical and effective method for investigating such a scenario. It allows for repeatable experiments and precise measurements, ensuring that Lillian can accurately determine the speed at which a train can safely navigate a specific curve.
