Homework Statement
A car traveling on a flat (unbanked), circular track
accelerates uniformly from rest with a tangential acceleration
of 1.70 m/s2. The car makes it one-quarter of
the way around the circle before it skids off the track.
From these data, determine the coefficient of static
friction between the car and the track.
Homework Equations
The Attempt at a Solution
The distance traveled by the car:
2r(pi)(1/4) = 1.57r
s = 1.57r, v = ?, u = 0, a = 1.7
v^2 = u^2 + 2as
v = (5.338r)^(1/2)
ac = (v^2)/r = 5.338
F = ma = [PLAIN]https://upload.wikimedia.org/math/9/3/9/939974a71dda1b83cce5ab82a2d2cec1.pngn
5.3388m = 9.8[PLAIN]https://upload.wikimedia.org/math/9/3/9/939974a71dda1b83cce5ab82a2d2cec1.pngm
what's wrong? Thanks!
