Homework Statement
angular velocity about the axle = 65 rads^-1
diameter = 0.54m
radius= 0.27m
1/2radius= 0.135m[/B]
Homework Equations
v=rw
w=θ/t
a=v^2/r=w^2r
(Might be the probability that i have to use another equation)[/B]
The Attempt at a Solution
Firstly i cut the diameter in half which gave me the radius of 0.27m
Then i cut it in half again(since i need ang.velocity between axle and outer edge)
which gave the radius of 0.135m
I am assuming that v=constant on all points on the wheel(this is where i may be wrong)
so what i did was v=0.27m*65rads-1
which gives v=17.55ms-1
since i am assuming v=constant everywhere
i arranged the formula w=v/r
which i did 17.55/0.135m=130rads-1
anyone can help me because I am almost sure that i have a wrong answer
Thanks[/B]
