SUMMARY

The horsepower calculation for a 2002 Honda Accord EX with a V6 engine and a curb weight of 2943 lbs at 55 mph is critically evaluated in this discussion. The initial value of 7.68 hp appears to be significantly lower than the recalculated estimate of approximately 16 hp. This discrepancy indicates potential errors in the data collection or calculation methods used to determine the drag coefficient. Accurate horsepower assessments are essential for reliable physics experiments involving vehicle dynamics.

PREREQUISITES
  • Understanding of basic physics principles related to drag coefficient

For a lab in physics where we have to go through an enormous process to calculate the drag coefficient, I am trying to figure out if one of the values I got along the way makes sense so that I don't continue with bad data.

I gathered time and speed deceleration data and drove a 2002 Honda Accord EX with a v6 engine, curb weight 2943 lbs.

For this car does a horsepower of 7.68 hp at 55mph sound reasonable?

I calculated it in a different way and got about 16 if that makes any more sense.

I'm sorry for my total lack of knowledge on this subject, I know I'm probably butchering the terminology, etc.
