Referring to the previous problem, (a) estimate the linear speed of a point on the rim of the rotating disk. (b) By comparing the arc length between the two white lines to the distance covered by the BB, estimate the speed of the BB. (c) What radius must the disk have for the linear speed of a point on its rim to be the same as the speed of the BB? (d) Suppose a1.0-g lump of putty is stuck to the rim of the disk. What centripetal force is required to hold the putty in place?

Speeding BB and spinning wheel. (Problem)
