Answer :
The maximum speed she can go without flying outward off the road is 46.47 m/s.
radius of the turn= 90m
coefficient of friction between the road and tire = 0.4
coefficient of friction
The ratio between the normal force pressing two surfaces together and the frictional force preventing motion between the two surfaces.
- it is denoted as[tex]\mu_s[/tex].
- Mathematically, μs = F/N.
- where, F is the frictional force and N is the normal force.
Then to find out the speed we can calculate it as :
[tex]v = \sqrt{ r * g* \mu_s }[/tex]
[tex]v = \sqrt{ 90* 10* 0.4 }[/tex]
v = 46.47 m/s.
The maximum speed she can go without flying outward off the road is 46.47 m/s.
