A ball is dropped from rest from a high window of a tall building and falls for 4 seconds. Neglecting air resistance, the final velocity of the ball is?
Answer:
The final velocity of the ball is 39.2 m/s.
Explanation:
Given that,
A ball is dropped from rest from a high window of a tall building.
Time = 4 sec
We need to calculate the final velocity of the ball
Using equation if motion
[tex]v=u+gt[/tex]
Where, v = final velocity
u = initial velocity
g = acceleration due to gravity
t = time
Put the value into the formula
[tex]v=0+9.8\times4[/tex]
[tex]v=39.2\ m/s[/tex]
Hence, The final velocity of the ball is 39.2 m/s.
Carlos runs with velocity \vec{v}v →= (5.6 m/s, 29o north of east) for 10 minutes. How far to the north of his starting position does Carlos end up? (Give your answer to the nearest meter)
Answer:
1629 metres
Explanation:
Given that Carlos runs with velocity v = (5.6 m/s, 29o north of east) for 10 minutes.
To the north, the velocity will be:
V = 5.6 × sin 29
V = 2.715 m/s
Convert the time to second
Time = 10 × 60 = 600
Using the formula below
Velocity = distance/ time
Substitute all the parameters into the formula
2.715 = distance/600
Distance = 2.715 × 600
distance = 1629 m

Why is it important to describe motion in universal terms?
Answer:
Motion requires force to cause that change. The time you take to travel the distance depends upon speed; the distance travelled is measured as the length of a line between the start and end of a motion. It is an important aspect in physics. In our lives motion is important and impacts so many things that we do.
Explanation:
The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.
The motion of an object occurs when there is change in the position of the object with time and the object moves in the direction of the applied force. This motion is influenced by the net force acting on the object.
For example:
The dimension of speed of object in motion is measured with two fundamental quantities (length and time);
speed = LT⁻¹
The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.

A car with a mass of 1,200 kg travels a distance of 150 m as it moves from
one stoplight to the next. At its fastest, the car travels at 22 m/s. What is its
kinetic energy at this point?
A. 290,400
B. 8,872 J
C. 580,800 J
D. 13,200 J
Answer:
A. 290,400
Explanation:
The kinetic energy of a car is 290,400J.
How to find Kinetic energy?Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2.
ke = 1/2mv^2
By using the formula, we get
= 1/2 * 1200 * 22^2
= 600 * 484
= 290,400 J
Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

Refer to the position time graph provided to answer questions #1 thru 5.
1. What is the instantaneous velocity of the object at 5 s?
2. What is the distance the object moves from 0 to 9 seconds?
3. What displacement did the object have between 2 s and 9 s?
4. What was the object's average velocity over the first 5 seconds?
5. How many times does the object change direction of travel? (time zero
does not count and standing still does not count as a direction change)
Answer:
Explanation:
1). To calculate the instantaneous velocity of the object, we will calculate the slope of the line CD.
Since line CD is a straight line, therefore, slope = 0
Hence instantaneous velocity = 0
2). Distance of the object when it moves from 0 to 9 seconds
= Distance traveled from (A to B + B to C + C to D + D to E)
= 3 + (3 + 0.5) + 0 + 0.5
= 7 m
3). Displacement = Distance between initial and the final positions of the object
= 3 - 0
= 3 m
4). Average velocity = [tex]\frac{\text{Displacement}}{\text{Time}}[/tex]
= [tex]\frac{0.5}{5}[/tex]
= 0.1 m per sec
5). Direction changes have been seen at t = 2 sec and t = 4 sec.
Hence object changed its direction of travel 2 times.

Change in speed = 20 km/h
Acceleration = (20 km/h) / (4 h)
Acceleration = 5 km per hour-squared

Migration is affected by various factors like age, sex, marital status, education, occupation, employment etc. Age and sex are main demographic factors that affect the migration. Men, generally, migrate to other places quite often though there are more women who migrate to husbands' places after marriage.Answer:
Social aspect:
In the place of origin migration can create a lack of food, accomodation and other basic services and facilities. Because of influence of lanuage, tradition , culture etc carried by immigrants the native language culture and tradition of the target place may get endangered. This may create diverseness of culture language so there can be disunity and factionalism in society. Target place may have to experience unemployment and criminal activities may take a lead.The place of origin may have to suffer from depopulation and slow development as well..

What are significant figures?In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.
If a number describing the result of a measurement (such as length, pressure, volume, or mass) includes more digits than the number of digits permitted by the measurement resolution, only the digits allowed by the measurement resolution can be significant figures.
As given in the problem we have to convert 3 x 10⁻⁹ s into milliseconds
1 second = 1×10³ milliseconds
3 x 10⁻⁹ seconds = (3 x 10⁻⁹) × (1×10³ )
= 3 x 10⁻⁶milliseconds
Thus, 3 x 10⁻⁹ s converted into milliseconds it would be 3 x 10⁻⁶ milliseconds

A car starts to move from rest after 5 seconds its velocity becomes 15m/s, find the acceleration of the car.
Answer:
acceleration of the car is 3 m\s^2
Explanation:
from rest means the initial velocity (vi) is zero
time = 5s
final velocity (vf) = 15m\s
a = vf - vi \ t
a = (15-0) \ 5
a= 3 m\s^2
which means that the car is speeding up 3 meters every second
Answer:
3m/s
Simple
Explanation:
Solution,
U=0
Velocity=15m/s
Time=5 sec
Now,
Acceleration=V-U÷T
=15m/s-0÷5
=15m/s÷5
=3m/s
Hence, the acceleratiob of the car is 3m/s.

HELP ME PLZ!!!! I'LL DO ABSOLUTELY ANYTHING, AND I MEAN ANYTHING!!!!!!
Answer:
There are so many things that make human travel difficult.
Here are some ideas ;
1) Air and Water -Taking water and oxygen from the Earth is very expensive and very difficult. (Note that if there is lots of water, oxygen can be made from the water. Also, if there is carbon dioxide, oxygen can be made.)
2) Food - people will need to grow their own food on another planet - transportation to and from Earth is, again, too expensive. Plants need carbon dioxide and sunlight (real sunlight is best; artificial lighting will work, too.)
3) Energy - Human settlements will need to create their own energy. Energy can be created using the sun.
Note that these powers have their own advantages and disadvantages
4) Radiation - Radiation is harmful for people, plants and animals. On Earth, we are protected by a magnetic field and an atmosphere. Some planets and moons have neither; some have only one or the other. Very few have both. Some planets have very strong magnetic fields that create even more radiation. Crazy right .
5) Gravity - planets or moons with a lesser gravitational pull than the Earth will result in astronauts having smaller bone and muscle mass, which is a serious problem if they are to come back to Earth. The closer a planet's gravity is to Earth, the less of a problem this is.
6) Atmosphere - Some planets have no atmosphere while some have atmospheres that will crush people(Woah ) .It's easier to deal with low-pressure rather than high-pressure, but both are dangerous if there is an air leak.
7) Distance - the further a planet is from Earth, the harder it is to.
8) Temperature - The hotter or colder a planet is, the more energy it will take to change the temperature(and im not really sure how ).
Explanation:
A cannon is fired horizontally from the edge of a 100 meter tall cliff. The muzzle velocity of the cannon is 180 m/s . How far from the base of the cliff does the hall land?
A-.55m
B-813.16m
C-3673.47
D-700m
Answer:
B - 813.16 m
Explanation:
First, find the time it takes to land. Given in the y direction:
Δy = 100 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
100 m = (0 m/s) t + ½ (9.8 m/s²) t²
t = 4.52 s
Now find the distance traveled in that time. Given in the x direction:
v₀ = 180 m/s
a = 0 m/s²
t = 4.52 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (180 m/s) (4.52 s) + ½ (0 m/s²) (4.52 s)²
Δx = 813.16 m
