A 6.0cm diameter wheel is rolling along at 20 m/s What is the speed of a point at the front edge of the wheel? Im kinda lost here. Tha answer given in the back of the book is 28.3 m/s. I have no idea how to do this problem, though I know i must be missing something simple. I found [tex] /omega = 66.6 rad/s [/tex] After this I have no idea where to go. Im not asking for anyone to do the problem for me. I'm just asking for a hint to help me figure out where to go next. Thanks alot. I would show more work if i could but I just can't figure out where to go or what I'm missing. I know it must be something stupid. Thanks.
