Hi again guys, I am back with a bit of confusion in Physics again... sorry about that. I was able to do everything in my homework except this one problem. Your bicycle tires have a radius of 0.33 m. It takes you 850 seconds to ride 14 times counterclockwise around a circular track of radius 73 m at constant speed. (a) What is the angular velocity of the bicycle around the track? [bike]r = 0.33m 2pi*.33 [track]r = 73m 2pi*73*14 (14 times around) Wf = Wi + a*t Wf^2=Wi^2+2a*changeoftheta changeoftheta=Wit+.5*a*t^2 I am unsure where to start other than finding the circumference. :| Please help, I need to understand this. I feel like I am missing something obvious, because I figured out how to do all the other angular velocity problems.
