Does this horsepower for this car seem like the right value?

AI Thread Summary
The discussion focuses on evaluating the horsepower of a 2002 Honda Accord EX with a V6 engine, specifically questioning whether 7.68 hp at 55 mph is a reasonable figure. The user also calculated a different value of approximately 16 hp, indicating a potential discrepancy in their data. Concerns are raised about the accuracy of the drag coefficient calculations and the reliability of the gathered time and speed deceleration data. The user expresses uncertainty about their understanding of the terminology and calculations involved. Accurate horsepower values are crucial for ensuring valid results in their physics lab project.

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.

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
