Please Help!! The Graph In The Figure Shows The Position Of A Particle As It Travels Along The X-axis.

Answers

Answer 1

The uniform movement allows to find the average speed, for which the correct answer is:

        B) 1.3 m / s

Kinematics studies the movement of bodies, establishing relationships between position, velocity and acceleration. In the special case that the acceleration is zero the motion is called uniform motion.

        v = [tex]\frac{\Delta x}{\Delta t}[/tex]

Where v is the velocity, Δx is the position variation and Δt is the time variation in the analyzed interval.

In this case

         v = [tex]\frac{2.0 - (-2.0)}{4.0\ -1.0}[/tex]

          v = 1.33 m / s

In conclusion using the uniform motion ratios we can find that the correct answer for the average velocity is

        B) 1.3 m / s

You throw a ball straight up into the air at a velocity of 15 m/s. You want to know how high above your hand the ball will be at exactly 2.5 sec after you released it. You must SHOW ALL WORK to receive credit!!! Of the 5 motion variables - Vi, Vf, a, ΔX, and T, identify which one you are solving for and the magnitudes and directions of all of the others that are known: Which of the motion equations is best to use to determine the height of the ball? How high is the ball above your hand at 2.5 sec after you throw it?

Answers

Answer:

6.875m

Explanation:

Given

Velocity = 15m/s

Time = 2.5secs

Required

Distance above your hand the ball will be at exactly 2.5secs

using the equation of motion:

ΔX = ViT + 1/2aT²

ΔX is the distance

Vi is the velocity of the ball in air

a is the acceleration due to gravity

T is the time taken

Since the ball is thrown straight up, a = -g

ΔX = ViT - 1/2gT²

Substitute

ΔX = 15(2.5) - 1/2(9.8)(2.5)²

ΔX = 37.5-30.625

ΔX = 6.875m

Hence the ball will be 6.875m above your hand at 2.5secs after you throw it.

A jet airliner moving initially at 538 mph (with respect to the ground) to the east moves into a region where the wind is blowing at 937 mph in a direction 23 degrees north of east. What is the new speed of the aircraft with respect to the ground. Answer in units of mph

Answers

Answer:

The speed is "1447.576 mph".

Explanation:

The given values are:

Direction (north to east)

= 23°

Wind's speed

= 937 mph

Jet moving at a speed

= 538 mph

Now,

The velocity of jet airliner with respect to the ground will be:

⇒ [tex]v=v_{1}+v_{2}[/tex]

⇒ [tex]v=\sqrt{(538)^2+(987)^2+2(538)(937)\times Cos23^{\circ}}[/tex]

⇒    [tex]=1447.576 \ mph[/tex]

In the real world where some energy is transferred to the environment as heat and sound the rollercoaster will not reach the top of a second hill if identical height.

Answer: No, it couldn’t. Energy leaves the system in the form of heat as the roller coaster cars travel from the top of one hill to the next. The vehicles have less total energy, so the potential energy at the top of the second hill must also be less. The cars wouldn’t be able to achieve the height of the first hill.

HeLp AsAp!!!!!! How long would it take you to hop 30 meters based on your speed for the 5-meter trial? Show your work!

Hopping =

Distance-5 m

Time-3.41

Speed-1.46

Answers

Answer:

20.5s

Explanation:

Given parameters:

Distance = 30m

Unknown:

Time  = ?

Solution:

The time it will take to hop a distance of 30m using the speed for the 5m trial is the duration of the trip.

 The speed for the 5m trial  = 1.46m/s

Now;

    Speed  = [tex]\frac{distance}{time}[/tex]

      Distance = speed x time

      time  = [tex]\frac{distance }{speed}[/tex]

Input the parameters and solve;

     time  = [tex]\frac{30}{1.46}[/tex]   = 20.5s

A student throws a ball upward with a force of 50.0 Newtons. The ball reaches a maximum height of 15.0 meters in 2 seconds and then returns back to
his hands. What is the direction of the acceleration at the top?
There is no acceleration at the top
O The acceleration is directed upwards away from the Earth
O The acceleration is directed downwards towards the Earth
O None of the above

Answers

Answer:

A

Explanation:

Given that a student throws a ball upward with a force of 50.0 Newtons. The ball reaches a maximum height of 15.0 meters in 2 seconds and then returns back to

his hands. 

At maximum height which is the top, the velocity is equal to zero.

According to definition of acceleration, which says; the rate of change of velocity.

Since velocity equal zero, acceleration also will be equal to zero.

Therefore, there is no acceleration at the top.

how does shape of object affect friction

Answers

Answer:

There are three types of friction.

1. Slanting friction

2. Sliding friction

3. Rolling friction

In the first two types of friction, the body of the object will come in contact with the irregularities on the surface more than in the case of rolling friction, thus a heavy box in square shape will have more friction than a heavy-duty vehicle.

This is also the reason why all vehicles are having wheels as they reduce friction and makes transportation easier and many people suggest to use a small log of wood to be placed on the bottom of a heavy box with flat bottom so it can moved easily due to reduction of friction

If the object is in Circle shape then you the friction a flat bottom then it will have increased friction

A wagon with a mass of 35 kg is pulled so that it accelerates from 0 m/s to 30 m/s in 15
seconds.
Remember to show all work!
a. What is the acceleration of the wagon?


b. What is the force required to get this acceleration?


Plz help me

Answers

Explanation:

a = v-u/t

a is the acceleration of the body

v is the final velocity

u is the initial velocity

t is the time

Given

v = 30m/s

u = 0m/s

t = 15secs

Substitute

a = 30-0/15

a = 30/15

a = 2m/s²

Hence the acceleration of the wagon is 2m/s²

b) Force = mass * acceleration

Given

Mas of the wagon = 35kg

acceleration a = 2m/s²

F = 35*2

F = 70N

Hence the force required to get this acceleration is 70N

Explanation:

A train rolls at a constant speed of 10 m/s across a horizontal track. A child standing on the flatbed of the train throws a ball so that it appears to move straight up to an observer standing next to the track. a. What is the horizontal speed of the ball relative to the observer?

Answers

Answer:

The answer is 10m/s

Explanation:

Given that the child is in the train, and that the train is moving at a speed of 10m/s, and also the child is standing on the flatbed, hence the child is not moving, therefore the velocity of the child is 10m/s relative to the observer

Also, when the child throws the ball horizontally relative to the observer the horizontal speed is also 10m/s.

therefore the speed of the ball is also 10m/s to the observer

find weight of 45 kg at height 800 km from earth's surface?​

Answers

Answer:

The weight is 348.4 N

Explanation:

Effect of the Altitude on the Acceleration of Gravity

The effect of gravity decreases with altitude because greater altitudes mean greater distances from the Earth's center.

The practical formula to calculate the gravity as a function of the altitude h is:

[tex]{\displaystyle g_{h}=g_{0}\left({\frac {R_{\mathrm {e} }}{R_{\mathrm {e} }+h}}\right)^{2}}[/tex]

Where go is the conventional gravitational acceleration = [tex]9.80665\ m/s^2[/tex]

R is the Earth's mean radius at the equator = 6,378 Km

h is the altitude.

At a height of h=800 Km, the acceleration of gravity is:

[tex]{\displaystyle g_{h}=9.80665 m/s^2\left(\frac {6,378 Km }{6,378 Km+800Km}}\right)^{2}}[/tex]

Calculating:

[tex]g_h=7.74\ m/s^2[/tex]

The weight is the product of the acceleration of gravity by the mass of the object, thus:

[tex]W=45\ Kg\cdot 7.74\ m/s^2=348.4\ N[/tex]

The weight is 348.4 N

A driver of a car traveling at -15m/s applies the brakes, causing a uniform acceleration of +2.0m/s2. If the brakes are applied for 2.5s, what is the velocity of the car at the end of the braking period? How far has the car moved during the braking period?

Answers

Given :

Initial velocity, u = -15 m/s.

Acceleration , a = 2 m/s².

Time taken to applied brake, t = 2.5 s.

To Find :

The velocity of the car at the end of the braking period.

How far has the car moved during the braking period.

Solution :

By equation :

[tex]v = u+at\\\\v=-15 + 2\times 2.5\\\\v=-10 \ m/s[/tex]

Now, distance covered by car is :

[tex]s=ut+\dfrac{at^2}{2}\\\\s=(-15)(2.5)+\dfrac{2(2.5)^2}{2}\\\\s=-31.25\ m[/tex]

Hence, this is the required solution.
