hi bee-gee! welcome to pf!

you obviously know how to find the

i suppose you could use that to draw a speed-time graph, and then measure the slope of [STRIKE]area under[/STRIKE]

alternatively, if you can measure the radius of curvature, r,

now put the rocket in a constant horizontal wind, so that

hi bee-gee! welcome to pf!

you obviously know how to find thespeed(from the area under the graph)

Isn't speed the slope of a distance / time graph?

To find the

The simplest thing to do is to approximate the speed, at a number of points using the difference quotient of a number of near by points. Then, again, repeat the process to find the second derivative.
