A horse is grazing for food. It trots rightward 15 m to eat a carrot, then walks rightward 20 m, to another carrot, then turns leftwards to walk 4m, to bite an apple. The horse walks a total time of 74 seconds. What is the magnitude of its average velocity?
(** HINT- you may want to draw this out, remember with VELOCITY direction matters-opposite vectors cancel out-with SPEED direction does not matter).
Answers
Answer:
0.42sExplanation:
Velocity = Displacement/time
Displacement of the horse is the distance covered in a specified direction
Total distance of the horse towards the right = 15m + 20m = 35m
Total distance of the horse towards the left = 4m
Displacement = Distance towards the right - Distance towards the left
Displacement = 35m-4m
Displacement = 31m
Time taken = 74seconds
substitute the values gotten into the velocity formula
average velocity = 31m/74s
average velocity = 0.42m/s
Hence the magnitude of its average velocity is 0.42s

A giraffe, standing 6.00 m tall, bites a branch off a tree to chew on the leaves
and lets the branch fall to the ground. How long does it take the branch to hit
the ground?
Answers
Answer:
1.11 s.
Explanation:
From the question given above, the following data were obtained:
Height (H) = 6 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =.?
The time taken for the branch to hit the ground can be obtained as follow:
H = ½gt²
6 = ½ × 9.8 × t²
6 = 4.9 × t²
Divide both side by 4.9
t² = 6/4.9
Take the square root of both side
t = √(6/4.9)
t = 1.11 s
Therefore, it will take 1.11 s for the branch to hit the ground.

An airplane flies 33 m/s due east while experiencing a tailwind
of unknown velocity due north. The resultant velocity is
determined to be 35.11 m/s northeast. What is the velocity of
the northern tailwind?
Answers
Explanation:
Use Pythagorean theorem.
v² = vₓ² + vᵧ²
(35.11 m/s)² = (33 m/s)² + vᵧ²
vᵧ = 12 m/s
The velocity of the northern tailwind is 12 m/s.
To find the velocity of northern tailwind, the given values are,
Resultant velocity v = 35.11 m/s,
Velocity of plane vₓ = 33 m/s.
What is the resultant velocity?The resultant velocity of the plane is the sum of the velocities of the plane and the wind with the consideration of their directions. The sum of the vector forces on an object is equal to the scalar product of the object's mass and its acceleration vector.The plane heads east and the wind being a tailwind also heads north east. Hence, we add their values using Pythagorean theorem,Use Pythagorean theorem.
v² = vₓ² + vᵧ²
(35.11 m/s)² = (33 m/s)² + vᵧ²
vᵧ² = 35.11² - 33²
vᵧ² = 1232.71 - 1089
vᵧ = √143.71
vᵧ = 11.98 m/s
which can be vᵧ = 12 m/s
Hence, the velocity of the northern tailwind is vᵧ = 12 m/s.

Answers
Answer:
"Cold" in this case, is defined as a difference between the body temperature and the room/ambient temperature.
If the body temperature is higher than the room temperature, then the "sensors" in our skin will sense that the ambient temperature is lower than ours, then we feel "cold"
The room temperature is: 36.1°C.
The higher body temperature is the one of Shyam, 36.4°C
The difference is really small:
36.4°C - 36.1°C = 0.3°C
But still, he will feel the room a little cold for him

A farmer is attempting to take a chicken across a river in a motorboat while a fox waits on shore with a bag of grain. If the river has a current with a velocity of 2.0 m/s and the boat maintains a speed relative to the water of 4.5 m/s, in which direction (angle) should the farmer point the boat so that the boat follows a straight path directly across the river?
Answers
Answer:
The farmer should go approximately 26.39° relative to the direction of and toward the river current velocity or approximate 90 - 26.39 which is 63.12° clockwise from the perpendicular direction across the river
Explanation:
The given parameters are;
The river current velocity = 2.0 m/s
The boat speed relative to the water = 4.5 m/s
Therefore, for the boat to have a resultant velocity that will follow a straight path directly across the river, we have;
The water current velocity, 2 m/s, the relative speed of the boat, 4.5 m/s, and the resultant velocity, v, form a right triangle, with the water current being the base, and the boat's relative speed being the hypotenuse side, while the height is the resultant velocity
Therefore, we have;
The direction of the boat relative to the direction of current the river = θ
The relative speed of the boat × sin(θ°) = The river current velocity
∴ sin(θ°) = The river current velocity/(The relative speed of the boat)
Which gives;
sin(θ°) = 2 m/s/(4.5 m/s) = 2/4.5 = 4/9
θ = sin⁻¹ = sin⁻¹(4/9) ≈ 26.39°
Therefore, the farmer should go approximately 26.39° relative to the direction of and toward the river current velocity or approximate 90 - 26.39 which is 63.12° clockwise from the perpendicular direction across the river.

As the earth rotates through one revolution, a person standing on the equator traces out a circular path whose radius is equal to the radius of the earth (6.38×10^6). What is the average speed of this person in meters per second? If we are standing in latitude 43° north what is our average speed?
Answers
Answer:
The average speed will be "1038 mph".
Explanation:
Period for one revolution is:
T = 24 hours
= 86,400 sec
x = c = 2πr
The given values is:
r = 6.38×10⁶ m
Now,
⇒ [tex]T=\frac{2 \pi r}{v}[/tex]
Or,
⇒ [tex]v=\frac{2 \pi r}{T}[/tex]
On substituting the values, we get
[tex]=\frac{2 \pi (6.38\times 10^6)}{86,400}[/tex]
[tex]=464 \ min/sec[/tex]
[tex]=(464 \frac{min}{sec}) (\frac{3600 \ sec}{1 \ hour} )(\frac{1 \ mi}{1609 \ m} )[/tex]
[tex]=1038 \ mph[/tex]

Which example best represents balanced forces? an elevator stopped on the third floor a basketball shot into a hoop a sled sliding down a snowy hill a tow truck pulling a car out of a ditch
Answers
Answer:
an elevator stopping on the third floor
Explanation:
The example that best represent balanced force as regards this question is an elevator stopped on the third floor.
Balanced force can be regarded as resultant force that has a magnitude of zero when acted on an object. When forces that are been subjected on a body are zero then the force is balanced.In the case of the elevator, immediately it stopped at a particular floor, then it will gave a balanced force, because at that point all forces acting on it becomes zeroWhen a car is pushed from a ditch , the force is acting from a side so its not balancedExamples of balanced forces are;
The weight of object as well as normal force acting on it can be regarded as been balanced.When pushing a car at both opposite sides with the same forces.A lizard that hangs in vertical position.Therefore option A is correct, because balanced force exist as the elevator stopped.
