A ferris wheel with radius of 20 meters is rotating at a rate of 1 revolution every 3 min how fast is a rider rising when his seat is 24 m above ground level?

Answer 1

Here is an outline of the solution: Find the velocity of a point on the rim by multiplying the radius times the angular velocity in radians per second (converted from 1 rev per 3 min.). The direction of the rim velocity is tangent to the rim. You have to find the vertical component of this velocity using trig. You find the necessary angle to do this by drawing a radial line to the point on the rim that is 24 m above ground level. There are several parts to this problem, so good luck.
