A banked circular highway is designed for traffic moving

Nuetrik [128]

Answer:

0.063

Explanation:

velocity of the car, v = 40 km/h = 11.11 m/s

radius, r = 200 m

Let the coefficient of friction is μ.

The coefficient of friction relates to the velocity on banked road is given by

$\mu =\frac{v^{2}}{rg}$

where, v is the velocity, r be the radius of the curve road and μ is coefficient of friction.

By substituting the values, we get

$\mu =\frac{11.11^{2}}{200\times 9.8}$

μ = 0.063

I NEED HELP PLEASE, THANKS! Light passes from air into water at an angle of 40.0° to the normal. What is the angle of refraction

Vlad [161]

Answer:

Angle of Refraction = 28.9 degrees

Explanation:

We'll use Snell's law for this. It's mathematical form is:

=> $n_1* sin(\alpha _1)=n_2 * sin(\alpha _2)$

Where $n_{1} = 1, n_{2} = 1.33, \alpha _{2} = 40^o$

=> $n_{1}$ and $n_{2}$ are the refractive indexes of the air and water respectively.

Solution:

=> 1 * sin (40) = 1.33 * sin( $\alpha _{2}$ )

=> sin $\alpha _{2}$ = $\frac{sin 40^0}{1.33}$

=> sin $\alpha _{2}$ = 0.4821

=> $\alpha _{2}$ = 28.9 degrees

(b) Find the position, velocity, and acceleration of the mass at time t = 5π/6.

Juli2301 [7.4K]

Solution
x(t) = 8 cos t, x(5π/6)= 8 cos(5π/6)
cos(5π/6)=cos(3π/6 + 2π/6 )=cos(π/3 +π/2)= - sin π/3 (cos (x+π/2)= -sinx)
x(t) = -8sin π/3 = - 4 .sqrt3
v(t) = -8sint = -8sin (π/3 +π/2)= -8 cosπ/3 (sin (x+π/2)= cosx)
v(t) = -8 cosπ/3 = -8/2= - 4
a(5π/6) = - 8cost = -(- sin π/3)= 4 .sqrt3
a(5π/6) = 4 .sqrt3
