A car is traveling at 45.0 mi/h on a horizontal highway.
(a) If the coefficient of static friction between road and tires on a rainy day is 0.100, what is the minimum distance in which the car will stop?
(b) What is the stopping distance when the surface is dry and µs = 0.602?
but a= force/mass= mu*mg/m= mu*g
solve for distance d.
45 mi/h = 20.1168 m/s
a = .100(g)
solving for time
v=vo + at
solving for distance
