Find the maximum speed with which a car can round a curve that has a radius of 80 m without slipping if the road is unbanked and the coefficient of
friction between the road and the tires is 0.81.
20.8 m/s
25.2 m/s
44.3 m/s
30.6 m/s

25.2 m/s

Explanation:

∑F = ma

Nμ = m v² / r

mgμ = m v² / r

gμ = v² / r

(9.8 m/s²) (0.81) = v² / 80 m

v = 25.2 m/s

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
