Question

calculate the angular velocity in radians per minute of ferriswheel 250ft. in diameter that takes 45second to rotate once. express the answer in term of pie

Answer 1

the diameter of the wheel makes no difference.

The angular velocity is

2π rad / 45sec = 2π/45 rad/s

And that's <u>pi</u>, <b>not</b> <u>pie</u> !
