Math CentralQuandaries & Queries


Question from Kolade:

Krusty the Clown and Sideshow Bob have covered themselves in velcro, and shot themselves out of a large cannon so that they stick to a huge rotating velcro wheel (don’t try this at home). As shown in Figure 1(a), Krusty is now stuck to a point 3.00 m from the center of the wheel while Bob is stuck to another point 5.00 m from the center. The wheel is rotating counterclockwise at 10.0 rpm. Conveniently a set of axes is suspended just in front the wheel (Krusty asked for axes, like the ones you would use to chop wood, so that he and Bob could chase each other with them in the usual wholesome entertainment he is known for. Unfortunately, the set designer misunderstood.) The axes do not rotate with the wheel.
(a) Find Krusty’s and Bob’s angular velocities, in radians per second.

Hi Kolade,

You didn't end a diagram so here is mine. Krusty is at $K$ and Bob is at $B.$


The wheel rotates at 10 radian per minute. How many seconds are in a minute? The wheel rotates 10 radians in that number of seconds. How many radians per second is that?
