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.
