A car moves on a circular, flat track at a speed of 15.0 m/s. If the car's mass is 1150 kg, and the radius of the turn is 55.0 m, what is the frictional force between the car's tires and the road?(adsbygoogle = window.adsbygoogle || []).push({});

_____________

If the coefficent of static friction between the tires and the road is 0.930, what is the maximum speed that the car can have and still safely negotiate the turn?

_____________

is this what you need to do for the first part?

What do i need to do about the second part?

m = mass

u = coefficent of friction

g = 9.8 m/s^2

a = centripetal acceleration= (v^2)/r

r = radius

v = speed

To find the answer, you set

ΣF = ΣF

umg = ma

ug = (v^2)/r
