A rocket lifts vertically off the launching pad and reaches a final velocity of 450 m/s in 15 seconds. What is its acceleration
Answer:
The answer is 30 m/s²Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula
[tex]a = \frac{v}{t} \\ [/tex]
where
v is the velocity
t is the time
From the question
v = 450 m/s
t = 15 s
We have
[tex]a = \frac{450}{15} \\ [/tex]
We have the final answer as
30 m/s²Hope this helps you
Calculate: A baseball accelerates downward at 9.8 m/s2. The force pulling the ball downward is 1.4 N. What is the mass of the baseball?
[tex]\large{\underline{\underline{\red{\tt{\purple{\leadsto } AnsweR:-}}}}}[/tex]
Given : Acceleration of the ball is 9.8 m / s² . The pulling force is 1.4 N .
To Find : The mass of the ball .
Solution : It is given that a ball accelerates download with a acceleration of 9.8 m / s² . And the acting force is 1.4 N .
We know that , Force acting is equal to the product of mass and acceleration . That is ,
[tex]\boxed{\purple{\bf Force=mass\times acceleration}}[/tex]
⇒ Force = mass × accelerⁿ
⇒ 1.4 N = mass × 9.8 m / s²
⇒ mass = 1.4 N / 98 m/s²
⇒ mass = 14N / 98 m/s².
⇒ mass = 1/7 kg .
Hence the mass of the object is 1/7 kg ≈ 0.14 kg.

A dog is 60 m away while moving at a constant velocity of 10 m/s towards you. How Long will it be before the dog is close enough to your face?
Answer:
6 seconds
Explanation:
The answer is 6 because if the dog is going 10 m/s it will take 6 seconds to get from 60 meters away to you.
What is the relationship between the tilt of the Earth on its axis, latitude, and temperature?
Answer:
The combination of more direct rays of sunlight and more hours of daylight causes the hemisphere tilted toward the sun to receive more solar radiation and to have warmer temperatures. When the Northern Hemisphere is tilted toward the sun, latitudes between the equator and 90°N (the North Pole) are experiencing summer.

Can an object have a positive position, but a negative velocity? Explain your reasoning.
Answer:
Yes
Explanation:
A position describes the position of an object relative to the x/y-axis (or the four cardinal directions). A velocity is a vector quantity, defining speed with direction.
So if an object is in a positive position, it means they are in the positive x-axis direction (or wherever on the scale the positive values are stated to be) and if it has a negative velocity, it means said object is moving in the opposite direction of the positive x-axis. It is possible for the object to still be in the positive position as it's moving with a negative velocity
A dog is 60m away while moving at constant velocity of 10m/s towards you. Where is the dog after 4 seconds?
How is acceleration related to force when mass is constant, according to Newton's second law of motion?
Answer:
According to Newton's second law of motion, acceleration is directly proportional to force. As the force increases (when mass is constant), the acceleration increases. This can be shown in the following formula.
[tex]f = ma[/tex]
[tex]a = \frac{f}{m} [/tex]
f = force
m = mass
a = acceleration
According to Newton's second law of motion, acceleration is directly proportional to the force.
What is Newton's second law of motion?According to Newton's second law of motion, an object's change in velocity is influenced by the force being applied to it. An object must accelerate in order to change its velocity. The rate at which an object's velocity alters over time is known as its acceleration.
Since both acceleration and force are vector quantities, the acceleration of an object is determined by the direction of the applied force. How much a net force will alter an object's velocity is described by Newton's second law of motion.
According to Newton's second law of motion, an object's acceleration is directly proportional to the force acting on it.

You have about 10 quarts of blood in your body. At REST your heart pumps about 5 quarts each minutes. That is half of your blood volume per minute. During exercise it can pump 40 quarts per minute. How many times does all of your blood complete the cycle around your body during exercise?
Answer:
8 times
Explanation:
Given that You have about 10 quarts of blood in your body. At REST your heart pumps about 5 quarts each minutes.
That means the heart will pump 10 quarts in 2 minutes.
That is half of your blood volume per minute.
If during exercise it can pump 40 quarts per minute, that is, 80 quarts in 2 minutes.
To know how many times does all of your blood complete the cycle around your body during exercise, you must divide 80 quarts by 10 quarts. That is,
80 / 10 = 8
Therefore, your blood complete the cycle around your body 8 times during the exercise.
Coulomb's law describes how the charge on and distance between two
particles affect the electric force between them. Which situation will result in
the two particles being attracted to each other?
The situation in which one particle has a positive charge and one has a negative charge will result in the two particles being attracted to each other.
What is Coulomb's law?It states that the force between two charged particles is directly proportional to the product of the magnitude of the charges and inversely proportional to the square of the distance between them.
Given is Coulomb's law which describes how the charge on and distance between two particles affect the electric force between them.
From the properties of charges, we know that the like charges repel and unlike charges attract each other. This means that two positive charges will repel each other and two negative charges will also repel each other. However, if one positive and one negative charge are brought closer to one another, than they will attract each other.
Therefore, the situation in which one particle has a positive charge and one has a negative charge will result in the two particles being attracted to each other.

Complete question is;
A car is traveling along a straight road at a velocity of 36.0 m/s when its engine cuts out. For the next twelve seconds the car slows down, and its average acceleration is For the next six seconds the car slows down further, and its average acceleration is The velocity of the car at the end of the eighteen - second period is 28.0 m/s. The ratio of the average acceleration values is a1/a2 = 1.5.
Find the velocity of the car at the end of the initial twelve - second interval.
Your answer
Answer:
30 m/s
Explanation:
To solve this, we will use Newton's first equation of motion;
v = u + at
Since we are dealing with acceleration ratio, let's make a the subject;
a = (v - u)/t
For the first 12 seconds and initial velocity u = 36 m/s, we have;
a1 = (v - 36)/12
For the remaining 6 seconds, initial velocity is the final velocity from the initial 12 seconds. Thus;
a2 = (28 - v)/6
We are given that a1/a2 = 1.5
Thus;
[(v - 36)/12]/[(28 - v)/6] = 1.5
(6/12)((v - 36)/(28 - v)) = 1.5
(v - 36)/(28 - v) = 1.5 × 12/6
(v - 36)/(28 - v) = 3
v - 36 = 3(28 - v)
v - 36 = 84 - 3v
4v = 120
v = 120/4
v = 30 m/s
If a substance has a density of 2.7g/cm3 and a mass of 86.4g, what is its volume?
Answer:
32cm³
Explanation:
Given parameters:
Density of substance = 2.7g/cm³
Mass of substance = 86.4g
Unknown:
Volume of substance = ?
Solution:
Density is the mass per unit volume of a substance.
Density = [tex]\frac{mass}{volume}[/tex]
Since the unknown is volume we solve for it;
mass = density x volume
86.4 = 2.7 x volume
volume = [tex]\frac{86.4}{2.7}[/tex] = 32cm³
