what is the maximum speed at which automobile can round a curve of 100 ft radius on level if the coefficient of friction between the tires and the road is 0.35?

Answer 1

33.57 ft/s

Answer 2

Formula= mv^2/r=úN
ú-coefficient friction
N=mg

Given:
Radius=100ft
ú=0.35

Required: 100ft x 1m =30.48m
Velocit . 3.28ft

Solution:
mv^2/r=úmg - cancel m
v=√rúg
v=√(30.48m)(0.35)(9.8m/s^2)
v=10.22m/s
v=33.53ft/s
