where is the centripetal force directed on a banked curve?

Answers

Answer:

The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve.

Explanation:LET ME KNOW IF ITS WRONG. HAVE A NICE DAY!!!!!!!!!!

Answer: The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. In order for a car to move around a circular track, something must provide a centipetal force. One source of the centripetal force is friction between the tires and the road. This means that the tires do not need to supply any friction at all to keep the car from slipping sideways. ...

A construction crew must use a lever to lift a boulder. The mechanical advantage of the lever is 6 and the lever applies a force of 1600 N to the rock. What is the force that the construction crew must apply to the lever?

Answers

Answer:

The force the construction crew must apply to the lever is 266.67 N

Explanation:

Mechanical advantage is the measure of the ratio of output force to input force in a system. Hence, mechanical advantage (MA) is given by the formula

[tex]MA = \frac{F_{o} }{F_{i} }[/tex]

Where MA is the mechanical advantage

[tex]F_{o}[/tex] is the output force

and [tex]F_{i}[/tex] is the input force

From the question, the mechanical advantage of the lever is 6

That is, MA = 6

and the lever applies a force of 1600 N to the rock

That is, Output force, [tex]F_{o}[/tex] = 1600 N

To determine the force the construction crew must apply to the lever, that is the input force, [tex]F_{i}[/tex]

From

[tex]MA = \frac{F_{o} }{F_{i} }[/tex]

We can write that

[tex]F_{i} = \frac{F_{o} }{MA}[/tex]

Then,

[tex]F_{i} = \frac{1600N}{6}[/tex]

[tex]F_{i} = 266.67 N[/tex]

Hence, the force the construction crew must apply to the lever is 266.67 N.

The force that the construction crew must apply is 266.67 N.

A machine is a device in which the effort applied at one end is used to overcome a load at another end. The mechanical advantage is the ratio of load to effort of a machine.

We have the following information;

Mechanical advantage (MA) = 6

Load =  1600 N

Effort = ?

Substituting values;

6 = 1600N/Effort

Effort =  1600N/6

Effort =   266.67 N

The car's initial speed was 15 m / s and the distance the car travels before it comes to a complete stop after the driver applies the brakes is 63m. What is the magnitude of the car's acceleration?

Answers

Initial speed of the car (u) = 15 m/s

Final speed of the car (v) = 0 m/s (Car comes to a complete stop after driver applies the brake)

Distance travelled by the car before it comes to halt (s) = 63 m

By using equation of motion, we get:

[tex] \bf \longrightarrow {v}^{2} = {u}^{2} + 2as \\ \\ \rm \longrightarrow {0}^{2} = {15}^{2} + 2 \times a \times 63 \\ \\ \rm \longrightarrow 0 = 225 + 126a \\ \\ \rm \longrightarrow 126a = - 225 \\ \\ \rm \longrightarrow a = - \dfrac{225}{126} \\ \\ \rm \longrightarrow a = - 1.78 \: m {s}^{ - 2} [/tex]

[tex] \therefore [/tex] Acceleration of the car (a) = -1.78 m/s²

Magnitude of the car's acceleration (|a|) = 1.78 m/s²

A truck moving due south takes a turn and starts moving towards east while maintaining the same speed.
Its velocity remains constant.
It covers unequal distances in equal intervals of time.
Its velocity changes
None of the above

Answers

Answer:

Its velocity changes

Explanation:

When the truck changes direction, its velocity changes.

Velocity is a vector quantity that specifies the magnitude of motion and direction it is taking.

When direction changes, the velocity of a body will also change. This is unlike speed which is a scalar quantity.

 Velocity is the displacement divided by time taken.

Darius' boat sails into the harbor with a speed of 80m/s. After 20 seconds, Darius' boat has come to a stop at the dock. What is his boat's acceleration?

Answers

Answer:

The boat's acceleration is 4 m/s²

Explanation:

This question seeks to test the knowledge of acceleration and how to calculate acceleration when the speed is provided. Hence, the formula for acceleration would be used here.

Acceleration (m/s²) = speed (in m/s) ÷ time (in seconds)

Acceleration = 80 m/s ÷ 20 secs

Acceleration = 4 m/s² or 4 ms⁻²

The boat's acceleration is 4 m/s²

Explanation:

Given parameters:

Frequency = [tex]\frac{22}{7}[/tex]cycles/s

Speed of wave = 57m/s

Unknown:

Wavelength  = ?

Solution:

The speed of a wave is related to frequency and wavelength using the expression below;

         V = f x λ

V is the speed of the wave

f is the frequency

λ is the wavelength

  Insert the parameters and find λ;

        57  =  [tex]\frac{22}{7}[/tex] x λ

a bird is traveling west with a velocity of 8 m/s and momentum of 40 mg*m/s what's the birds mass?

Answers

Answer:

m = 5 [mg]

Explanation:

We must remember that the definition of linear momemtum is defined as the product of mass by distance.

P = m*v

P = momentum = 40 [mg*m/s]

m = mass [mg]

v = velocity = 8 [m/s]

Now clearing m:

m = P/v

m = 40/8

m = 5 [mg]

A bus initially moving at 20 m/s with an acceleration of -4m/s2 for 5
seconds. What is the displacement AND final velocity?

Answers

Answer:

50m; 0m/s.

Explanation:

Given the following data;

Initial velocity = 20m/s

Acceleration, a = - 4m/s²

Time, t = 5secs

To find the displacement, we would use the second equation of motion;

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

Substituting into the equation, we have;

[tex] S = 20*5 + \frac {1}{2}*(-4)*5^{2}[/tex]

[tex] S = 100 + (-2)*25[/tex]

[tex] S = 100 - 50[/tex]

Displacement, S = 50m

Next, to find the final velocity, we would use the third equation of motion;

[tex] V^{2} = U^{2} + 2aS [/tex]

Where;

V represents the final velocity measured in meter per seconds. U represents the initial velocity measured in meter per seconds. a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

[tex] V^{2} = U^{2} + 2aS [/tex]

[tex] V^{2} = 20^{2} + 2(-4)*50 [/tex]

[tex] V^{2} = 400 - 400[/tex]

[tex] V^{2} = 0[/tex]

Final velocity, V = 0m/s

Therefore, the displacement of the bus is 50m and its final velocity is 0m/s.

A 700-kg car, driving at 29 m/s, hits a brick wall and rebounds with a speed of 4.5 m/s. If the car was in contact with the wall for 0.30 s, what force did the wall exert on the car during the collision?

Answers

Answer:

57166.6N

Explanation:

Step one:

given data

mass=700kg

initial velocity u=29m/s

final velocity=4.5m/s

time t= 0.3second.

Step two:

The expression for the momentum is given as

FΔt=mΔv

make F subject of the formula

F=mΔv/Δt

Substitute our given data we have

F=700(29-4.5)/0.3

F=700*24.5/0.3

F=17150/0.3

F=57166.6N

the force is 57166.6N
