Answer:
I want to say 10 seconds but im not 1000% sure
Answer:
Average speed= distance traveled/ time taken.
Explanation:
You shouldn't need any formula, just use common sense. You dummy. It goes 20m 10h half a sec. DUH!!!
A batter pops a ball straight up (a) If the ball returns to the height from which it was hit 4.5 s later, what was its
initial speed? (b) Does the ball reach its maximum height 2.25s after it was hit, more than 2.25s after it was hit, or
less than 2.25s after it was hit? Explain. (c) Find the maximum height of the ball, as measured from the point
where it was hit.
Answer:
it depends on how hard and fast he hit the ball a baseballs terminal velocity, a baseball can reach a velocity of around 95mph

Below you will see diagrams showing a trip taken by Fred and a trip taken by Frank. For each person, find their distance, displacement, average speed, and average velocity from A to B. Each square is 10 meters wide, and use words like north, south, east, and west for direction.
The first thing Fred did was go south for 4 seconds. If he wanted to cut his average speed in half, how long should that southward motion last (assuming the other two motions happen in the same time as shown)? Explain your reasoning.
Would this amount of wait-time also have halved his average velocity?
Part A
The completed table of values of the motion of Fred and Frank are;
[tex]\begin{array}{|l|c|c|}&\mathbf{Fred's \ Trip}&\mathbf{Frank's \ Trip}\\\mathbf{Distance}&150 \, m&120 \, m\\\mathbf{Displacement}&30 \, m&50 \, m\\\mathbf{Average \ Speed}&15 \, m/s&10 \, m/s\\\mathbf{Average \ Velocity}&3 \ m/s&4.1 \overline 6 \, m/s\end{array}\right][/tex]
Part B
The time the southward motion should last is 14 seconds
The reason the above values are correct is as follows;
The total distance is given by summing the length of the sides of the square that lay along the path
Known parameters:
For Fred's Trip, we have;
Distance = 60 meters South + 30 meters East + 60 meters north = 150 meters The total distance = 150 meters
Required:
The displacement = 30 meters East
Average speed = Total distance/(Total time)
Total time = 4 sec + 3 sec + 3 sec = 10 sec
Average speed = 150 m/10 sec = 15 m/s
Average velocity = Displacement/Total time
Average velocity = 30 m/10 sec = 3 m/s
Known parameters:
For Frank's Trip, we have;
Distance = 30 meters North + 60 meters East + 30 meters south = 120 meters
The total distance of Frank's trip = 120 meters
Required:
The displacement = 50 meters East
Average speed = Total distance/(Total time)
Total time = 5 sec + 5 sec + 2 sec = 12 sec
Average speed = 120 m/12 sec = 10 m/s
Average velocity = Displacement/Total time
Average velocity = 50 m/12 sec = 4.1[tex]\overline 6[/tex] m/s
Therefore, we have;
[tex]\begin{array}{|l|c|c|}&\mathbf{Fred's \ Trip}&\mathbf{Frank's \ Trip}\\\mathbf{Distance}&150 \, m&120 \, m\\\mathbf{Displacement}&30 \, m&50 \, m\\\mathbf{Average \ Speed}&15 \, m/s&10 \, m/s\\\mathbf{Average \ Velocity}&3 \ m/s&4.1 \overline 6 \, m/s\end{array}\right][/tex]
To reduce his speed in half, we have;
New average speed, s₂ = s₁/2
∴ s₂ = (15 m/s)/2 = 7.5 m/s
Let x represent the time for the southward motion, we have;
(150)/(6 + x) = 7.5
(6 + x) × 7.5 = 150
x = (150 - 7.5×6)/7.5 = 14
Therefore, the time for the southward motion should last for 14 seconds

How does the distance traveled by the coin compare to its displacement after ten flips?
Answer:
To calculate displacement, simply draw a vector from your starting point to your final position and solve for the length of this line. If your starting and ending position are the same, like your circular 5K route, then your displacement is 0. In physics, displacement is represented by Δs.

Which of the following statement is correct
The density of an object does not remains same if we take small quantity of that substance.
The density of an object remains same irrespective of its shape, size and quantity.
The density of an object does not remains same irrespective of its shape and size.
The density of an object remains same only if its shape and size remains same.
The density of an object remains same irrespective of its shape, size and quantity.
Explanation:
Density is an intensive property. This means that regardless of the object's shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density. It is because density in an intensive property of matter.
