A banked circular highway is designed for traffic moving

Physics
1 answer:
Nuetrik [128]4 years ago
3 0

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

What is the weight of a 2.06 kg text book. show work please
salantis [7]

The weight of anything is (mass) x (gravity in the place where the thing is).

             Gravity on Earth is about 9.8 newtons per kilogram, so on Earth,
             the weight of the book is

                          (2.06 kg) x (9.8 N/kg) = <em>20.19 newtons</em> .


Another way to get around it is:  

               On Earth, 1 kg of mass weighs about 2.205 pounds, so on earth,
               the weight of the book is

                         (2.06 kg) x (2.205 pounds/kg) = <em>4.54 pounds </em>.

How does the speed of light change as the index of refraction increases?.
Maksim231197 [3]

\huge{\green}\fcolorbox{blue}{cyan}{\bf{\underline{\red{\color{red}Answer}}}}

  • So as the index of refraction value increases, the optical density increases, and the speed of light in that material decreases.

If a loaded truck that accelerates at 1 meter per second squared loses its load and has three-fourths of the origional mass, wha
Nina [5.8K]
I believe it'd accelerate at 1.25 m/s^2 instead of 1, as it lost 1/4 of its mass (.25), so now it is .25 of 1 faster.

A uniform ladder of length l rests against a smooth, vertical wall. If the coefficient of static friction is 0.50, and the ladde
Ronch [10]

Answer:

X = 5.44 m

Explanation:

First we can calculate the normal force acting from the floor to the ladder.

W₁+W₂ = N  

W1 is the weigh of the ladder

W2 is the weigh of the  person

So we have:

m1g+m2g=N  

N=755.37 N

The friction force is:

F_{force}=\mu N=0.5\cdot 755.37=377.68 N

Now let's define the conservation of torque about the foot of the ladder:

\tau_{ledder}+\tau_{person=\tau_{reaction}}

m_{1}\cdot g\cdot X \cdot cos(53)+m_{2}\cdot g\cdot 3.75 \cdot cos(53)=F_{force}7.5sin(53)

Solving this equation for X, we have:

X = \frac{377.68\cdot 7.5\cdot sin(53)-21\cdot 9.81\cdot 3.75 \cdot cos(53)}{56\cdot 9.81\cdot cos(53)}

Finally, X = 5.44 m

Hope it helps!
