Homework Statement
I am running to school at 6m/s when I hit a patch of icy sidealk. The coefficient of friction between the ice and my shoes is 0.16. I wish to turn my 55kg frame to the left. What is the smallest turn I can make?
v = 6 m/s
μ = 0.16
m = 55 kg
Homework Equations
Fnet = mv^2/r
Ff = μFn
Fnet = ma
The Attempt at a Solution
Assume that up and left are positive.
Fnet = ma
Fg + Fn = ma
-539 + Fn = 0
Fn = 539
Ff = μFn
Ff = 0.16 (539)
Ff = 86.24
Fnet = mv^2/r
Ff = mv^2/r
86.24 = 55(6)^2/r
86.24 = 1980/r
r = 23 m
I'm not sure if that's the answer or what to do next, or even if what I did is the right method. The question is kind of confusing me because I don't fully understand how the person is moving.
