Answer:
Maximum speed of the car is 17.37 m/s.
Explanation:
Given that,
Radius of the circular track, r = 79 m
The coefficient of friction, [tex]\mu=0.39[/tex]
To find,
The maximum speed of car.
Solution,
Let v is the maximum speed of the car at which it can safely travel. It can be calculated by balancing the centripetal force and the gravitational force acting on it as :
[tex]v=\sqrt{\mu rg}[/tex]
[tex]v=\sqrt{0.39\times 79\times 9.8}[/tex]
v = 17.37 m/s
So, the maximum speed of the car is 17.37 m/s.
