A bit OT, math related
We try to keep our brains sharp around here. Those who know physics can see
that this problem, which I plan to present to my friends' son who is attending college right now is just a little brain exercise, but I would also like to know if I came up with the right answer. Part of the calculation bears similarity to figuring out paralell resistance and series capacitance, so, while a bit OT it is not out in left field.: ________________ An amusement park ride accelerates in a horizontal direction to a speed of 120 mph in 4 seconds. What is the average G effective force experienced by the rider during that time ? What is the force vector, using that figure, as compared to a line perpendicular to the ground ? _________ I came up with 2 2/3rd Gs. If necessary, I'll "show my work" in a followup. The second part I have not yet calculated, but my guess is around 52 degrees. To me, this is much better than discussing the last episode of "Friends" or some dumb crap like that. JURB |
