How large must the coefficient of static friction be between the tires and the road if a car is to round a level curve of radius 90 m at a speed of 90 km/h ?

Answers

Answer:

The coefficient of static friction will be 0.7

Explanation:

Given data

the radius of curve= 90m

speed v= 90 km/h to m/s = (90*100)/60*60=  25 m/s

we know that the expression for the centripetal force acting on the car

[tex]Fc= \frac{mv^2}{r}[/tex]-------1

we also know that the expression for the frictional force between road and tire.

Ff= μmg--------2

Equating equation 1 and 2 we have

μmg= mv^2/r

μ= v^2/gr

substituting the values of speed and radius we have (assuming g= 9.81m/s^2)

μ= 25^2/9.81*90

μ= 625/882.9

μ= 0.7

A moving object is in equilibrium. Which best describes the motion of the object if no forces change?

What does it mean when an object is in equilibrium?

If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object and the object is said to be in equilibrium.

What does equilibrium mean in physics?

A cliff diver from the top of a 100 (m) cliff. He begins his dive by jumping up with a velocity of 5 (m/s) a. How
long does it take for him to hit the water below? b. What is his velocity right before he hits the water?

Answers

Answer:

A.) 4.81 seconds

B.) 44.6 m/s

Explanation:

He begins his dive by jumping up with a velocity of 5 (m/s).

Let us first calculate the maximum height reached by using third equation of motion

V^2 = U^2 - 2gH

At maximum height, V = 0

0 = 5^5 - 2 × 9.8H

19.6H = 25

H = 25 /19.6

H = 1.28 m

The time taken for the diver to reach the water from the maximum height can be calculated by using second equation of motion.

Where height h = 1.28 + 100 = 101.28 m

h = Ut + 1/2gt^2

As the diver drop from maximum height, U = 0

101.28 = 1/2 × 9.8 × t^2

4.9t^2 = 101.28

t^2 = 101.28/4.9

t^2 = 20.669

t = sqrt ( 20.669)

t = 4.55s

As the diver jumped up, the time taken to reach the maximum height will be

Time = 1.28 / 5 = 0.256

The time taken for him to hit the water below will be 0.256 + 4.55 = 4.81 seconds

B.) Velocity right before he hits the water will be

V^2 = U^2 + 2gH

But U = 0

V^2 = 2 × 9.8 × 101.28

V^2 = 1985.09

V = 44.6 m/s

A.) The time taken should be 4.81 seconds

B.) The velocity should be 44.6 m/s

Calculation of the time taken and velocity:

Here we used third equation of motion

V^2 = U^2 - 2gH

At maximum height, V = 0

Now

0 = 5^5 - 2 × 9.8H

19.6H = 25

H = 25 /19.6

H = 1.28 m

Here the second equation of motion.

Here height h = 1.28 + 100 = 101.28 m

So,

h = Ut + 1/2gt^2

Since the diver drop from maximum height, U = 0

So,

101.28 = 1/2 × 9.8 × t^2

4.9t^2 = 101.28

t^2 = 101.28/4.9

t^2 = 20.669

t = sqrt ( 20.669)

t = 4.55s

Now

Time = 1.28 / 5 = 0.256

Finally the time should be

=  0.256 + 4.55

= 4.81 seconds

B.)

We know that

V^2 = U^2 + 2gH

But U = 0

So,

V^2 = 2 × 9.8 × 101.28

V^2 = 1985.09

V = 44.6 m/s

Percy threw a penny straight down off the Empire State building. The building is 354 m tall. If he threw the penny down such that it left his hand at 35 m/s, what is the acceleration of the penny? What will the velocity of the coin that Percy threw be when it hits the pavement?

Answers

Answer:

90.4 m/s

Explanation:

Take down to be positive.  For objects in free fall, the acceleration is 9.8 m/s².

Given:

Δy = 354 m

v₀ = 35 m/s

a = 9.8 m/s²

Find:

v² = v₀² + 2aΔy

v² = (35 m/s)² + 2 (9.8 m/s²) (354 m)

v = 90.4 m/s

Si la aceleración de gravedad en la superficie del planeta Mercurio es de 3,7 m/s2, entonces ¿cuál sería el peso de una persona de 60 kg de masa que se encuentre sobre su superficie?

Answers

Answer:

W = 222 N.

Explanation:

The qiestion says" If the acceleration of gravity on the surface of the planet Mercury is 3.7 m / s2, then what would be the weight of a person with mass 60 kg on its surface? "

Mass of the person, m = 60 kg

The acceleration due to gravity on the surface of gravity is 3.7 m/s²

We need to find the weight of a person on the surface of Mercury.

Weight of an object is given by :

W = mg

So,

W = 60 kg × 3.7 m/s²

W = 222 N

Hence, the person will weigh 2222 N on the surface of Moon.

The  positive feedback influence the stability of a system is:  It can cause the system to remain stable as long as inputs are constant. Hence, option (A) is correct.

What is stability ?

A body's capacity to return to its initial static equilibrium after being slightly shifted is referred to as stability.

A body in equilibrium doesn't suffer linear acceleration or a turning effect, and unless a force from the outside disturbs it, it will stay in that state forever. (The First Law of Newton)

When tiny, externally induced displacements from an equilibrium result in forces or torques that tend to oppose the displacement and bring the body back to its initial equilibrium, the equilibrium is said to be stable.If even the smallest deviations result in forces or torques that tend to increase the displacement, the equilibrium is said to be unstable.

differences between a pair of scissors and nailcutter​

Answers

Answer:

Different classes of levers

Explanation:

The main difference between a pair of scissors and nailcutters is that they are different classes of levers. Scissors are made from two class 1 levers, meaning that the effort is exerted at one end and the load at the other with the fulcrum in the middle. This is because we press one end together (the handles) so we are applying the effort, and the other side closes from the fulcrum in the middle.

Nailcutters on the other hand, consist of two class 2 levers. This means that the fulcrum is on the opposite end to the effort with the load in the middle. This is because we press down on one side and the two parts move closer together.
