Power = Force * Velocity. Under constant power, as your velocity increases, the force decreases and therefore the acceleration decreases.Brad331https://www.blogger.com/profile/04335200304537742054noreply@blogger.comtag:blogger.com,1999:blog-6177067188573803264.post-690202668527184412017-01-20T23:30:05.772+00:002017-01-20T23:30:05.772+00:00why do you use the equation h=0.5at^2 etc to calcu...why do you use the equation h=0.5at^2 etc to calculate height?Anonymoushttps://www.blogger.com/profile/10085125371807031288noreply@blogger.comtag:blogger.com,1999:blog-6177067188573803264.post-20676233862380205582016-09-07T18:34:17.835+01:002016-09-07T18:34:17.835+01:00The math is wrong.

To get the number of chairs, take the one way length divided by the spacing.
