Question: What is Tina's speed as she passes David?

Answer: Much less than you'd calculate.

If David had any sense, David would slow the hell down because Tina is either The Fuzz or Tina's packin' some serious horsepower.

Goddammit David. Don't mess with Tina.

Steady 1/4 g is not to be sneezed at. Of course, for that to be a constant rate, it would have to be a CVT. Maybe. Either that or Tina never got out of first.

probably an electric car. Even in first, the power curve would make acceleration not constant.

How is this ethics? also, her speed is 0.

There is no question posed.

It also does not state in which direction Tina is accelerating. If the unstated question is 'when does she reach David?' The answer is probably never, she was headed in some other direction. It's the 'going to St. Ives' question.

Edit: saw the question in the text. Rest still stands.

Well, enough cars have a linear-ish power curve in the region of interest that it wouldn't *have* to be an electric to be close. Ford Scorpio TDI below: pretty damn linear in power output increase per revs all the way to 3500 RPM.

it would have to be flat, not just linear *the torque curve would have to be flat*

Ideally. However, having a linear power curve is *close enough* if there is a torque converter is doing its job. Any type of torque conversion mutes non-linearity in the torque curve to the point it doesn't have that much impact if you're examining the problem for a *period* in which acceleration is taking place - power delivery just needs to be *mostly* steadily increasing.

If you insist, though, we can specify an Audi V10 delivering between 1500 and 6200, because computer limits are pure comedy.

daaaaaaamn thats a flat curve.
