Originally this problem is on centrifugal force, and I could solve it in one line.
But since the units are not metric, it is more conversion units problem, than Physics or Math problem.
90% of the solution work is the unit conversion!!
Had it has any sense, I'd solve it.
But to spend my time for a nonsense work . . . Brrrr! No.
My grandson studies Physics at high school.
Thanks to god, they use only the metric system.
No feet, no miles, no lbs.
It is difficult for me to imagine that somebody uses miles, feet and lbs in that kind of problems in our days!
In the XXI-century?
