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.

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

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

1 Kilocalories = 4,184 Joules

Answer:

The relationship between calorie and joule are proportionate. Which implies, the calorie is directly proportional to the joule. That means-

When the value in terms of calorie increases, its corresponding value in joules also increases at a rate of 4.2.

When the value in terms of calorie decreases, its corresponding value in joules also decreases at a rate of 4.2.

Answer:

The way in which objects exert forces on each other is described by Newton’s 3rd law of motion

Explanation:

Objects with mass exert forces on each other via the force of gravity. This force is proportional to the mass of the two interacting objects and is inversely proportional to the square of the distance between them. The factors G, M, and rare the same for all masses at the surface of the Earth.

Answer: His third law states that for every action, or force, in nature there is an equal and opposite reaction.

Explanation: Basically, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Hope it helps!

Answer:

His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.

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

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. ...

Answer:

18.14m

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

       λ = 57 x [tex]\frac{7}{22}[/tex]   = 18.14m

Answer:

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

Answer:

The mechanical advantage of a machine is 2. Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 2 means that for example if you apply 100 N then your machine will multiply that force and generate 200 N .

Answer:

Explanation:

Well, lets say you park your car on the top of a hill, gravitational energy prevents it from the car falling back. Or a snow pack, aka before a potential avalanche. Though gravity cannot keep it safe forever, gravitational energy keeps it from crashing asap. In this case, it gives you time to escape. Altogether, gravitational force keeps the earth in it's atmosphere.

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;

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.
