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.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
