A box is being pushed across the floor at a constant velocity with an
applied force of 30N, what is the magnitude of the frictional force acting
on this box?
Answers
Answer:
Magnitude of frictional force = 30 N
Explanation:
According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:
Fn=m.a
The net force is the vector addition of each individual force. If the sum of all the forces acting on an object is zero, then the acceleration is zero. That means the object moves at a constant speed or is at rest.
When an object is pushed across a horizontal rough surface, there are two forces acting in the direction of the motion: The applied force and the frictional force.
If the applied force is greater than the frictional force, then the object moves at a constant positive acceleration. If the frictional force is greater than the applied force, then the object won't move at all (if it was at rest) or will start a deaccelerated motion (braking).
Finally, if both forces are equal, the object will move at a constant speed or remains at rest. Since the box is moving at a constant speed, we can conclude the frictional force equals the applied force:
Magnitude of frictional force = 30 N

Problem #2: An apple is thrown upward with an initial velocity of +24.0 m/s. a. Sketch the apple's trip and label what you know. b. How high will the apple go? (Ans: +29.4 m) c. What is the total time needed for the apple to return to its original position? (Ans: 4.90 s)
Answers
Answer:
The answer is below
Explanation:
a) The initial velocity (u) = 24 m/s
We can solve this problem using the formula:
v² = u² - 2gh
where v = final velocity, g= acceleration due to gravity = 9.8 m/s², h = height.
At maximum height, the final velocity = 0 m/s
v² = u² - 2gh
0² = 24² - 2(9.8)h
2(9.8)h = 24²
2(9.8)h = 576
19.6h = 576
h = 29.4 m
b) The time taken to reach the maximum height is given as:
v = u - gt
0 = 24 - 9.8t
9.8t = 24
t = 2.45 s
The total time needed for the apple to return to its original position = 2t = 2 * 2.45 = 4.9 s
If you run east for 38m, stop suddenly, run another 27m east, then you run west for 47
m, what is your total displacement?
how to answer: #m, direction
Answers
Answer:
Total Displacement = -18m
Explanation:
Given
East Movement = 38m and 27m
West Movement = 47m
Required
Determine the total displacement
To answer this, we consider east as negative direction and the west as positive (using logics of number line).
Total Displacement = East Movement + West Movement
Total Displacement = -38m - 27m + 47m
Total Displacement = -18m
Hence, the total displacement is 18m towards East

Answer: The answer to 3 to is less inertia. The answer to 4 is large amount of inertia. The answer to 5 is large amount of inertia. The answer to 6 is more fuel. Number 6 is kind of unkown considering I can’t see the other answer but I guess it’s more fuel.
Explanation: Inertia is the resistance of the object to any change in its motion, including a change in direction. An object will stay still or keep moving at the same speed and in a straight line, unless it is acted upon by an external unbalanced force. So when there is more inertia, it’s harder to control, but when it has less inertia, it’s more loose and easier to move around.
How can Newton's third law describe the forces affecting a rocket as it
descends to Earth's surface?
A. The rocket can move downward because the forces acting on it
are unbalanced.
B. The maximum amount of force the rocket engines can provide

C. The rocket pushes through the air with a force equal to that of
Earth's gravity pulling on the rocket.
D. The force the rocket exerts on the air is in the direction opposite to
the force that the air exerts on the rocket.

The force the rocket exerts on the air is in the direction opposite to
the force that the air exerts on the rocket.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Every action has an equal and opposite response, according to Newton's Third Law. Burning fuel in a rocket causes a push that propels the rocket forward from the front. As a result, the exhaust gas is pushed in the opposite direction and equally.
The force the rocket exerts on the air is in the direction opposite to
the force that the air exerts on the rocket.

An ecosystem is a geographic area where plants, animals, and other organisms live in and interact with each other in an environment.
Forests are homes to orangutans, elephants, tigers, and other animals.
As more than 8.6 million acres of forest were destroyed in Indonesia, Malaysia, and Papua New Guinea to build palm oil plantations, this may lead to the following consequences:

c. all the forces exerted on the object, but not by it
d. all forces that exist within the neighborhood of the object
Answers
Answer:
C
Explanation:
A free-body diagram shows all the forces exerted or applied on an object.
A free-body diagram includes all the forces exerted on or by the object. Hence, option A is correct.
What is a free-body diagram?A free-body diagram is a diagrammatic representation of a single body or a group of bodies that are separated from their surroundings and display all the forces acting on them. A free-body diagram (FBD; sometimes known as a force diagram) is a graphical representation used in physics and engineering to show the applied forces, moments, and consequent reactions on a body under a specific condition.
It shows a body or group of connected bodies along with all the applied forces, times, and reactions that the body experiences. The body could be compact or comprise several interior pieces (like a truss) (such as a beam). To answer difficult problems, a series of free bodies and other diagrams may be required.
Hence, all the forces exerted on or by the object are included in the free-body diagram.

How far will a 600kg boat travel in 12 s if there is a constant 900N force on it and it starts from rest?
Answers
Answer:
d = 108 m
Explanation:
Given that,
Initial speed, u = 0
Mass of the boat, m = 600 kg
Time, t = 12 s
Force on boat, F = 900 N
Firstly, we can find the acceleration of the boat using formula, F = ma
[tex]a=\dfrac{F}{m}\\\\a=\dfrac{900\ N}{600\ kg}\\\\a=1.5\ m/s^2[/tex]
Let it will travel d distance. Using second equation of motion to find it as follows :
[tex]d=ut+\dfrac{1}{2}at^2\\\\d=0+\dfrac{1}{2}\times 1.5\times (12)^2\\\\d=108\ m[/tex]
So, the boat will travel 108 m.

Answer:
v = 0.0251 km/h
Explanation:
Given that,
The average distance from its center of mass of 1000 meters.
The time taken is 24 hours and 57 minutes to complete one orbit
We need to find the orbital velocity of the spacecraft OSIRIS-REx.Let it is v. SO,
[tex]v=\dfrac{2\pi r}{t}[/tex]
Putting all the values,
[tex]v=\dfrac{2\pi \times 100}{24\ hours\ and\ 57\ minutes}\\\\v=\dfrac{2\pi \times 100}{(86400+3420)}\\\\v=0.00699\ m/s[/tex]
or
v = 0.0251 km/h
So, the average orbital velocity is 0.0251 km/h.
