Answer:
1.7323
Explanation:
To develop this problem, it is necessary to apply the concepts related to refractive indices and Snell's law.
From the data given we have to:
Where n means the index of refraction.
We need to calculate the index of refraction of the liquid, then applying Snell's law we have:
Replacing the values we have:
Therefore the refractive index for the liquid is 1.7323
1) Available force of friction: 6174 N
2) No
Explanation:
1)
The magnitude of the frictional force between the car's tires and the pavement of the road is given by
where
is the coefficient of friction
m is the mass of the car
g is the acceleration of gravity
For the car in this problem, we have:
(coefficient of friction)
m = 1260 kg (mass of the car)
Therefore, the force of friction is
2)
In order to mantain the car in circular motion, the force of friction must be at least equal to the centripetal force.
The centripetal force is given by
where
m is the mass of the car
v is the tangential speed
r is the radius of the curve
In this problem, we have
m = 1260 kg
is the tangential speed
r = 41.6 m is the radius of the curve
Therefore, the centripetal force is
Therefore, the force of friction is not enough to keep the car in the curve, since
