2. A ball is dropped from a height of 52 m. The ball falls freely and reaches the ground in 75 s. What was the average speed of the ball?
Answer:
v = 0.69 m/s
Explanation:
Given that,
A ball is dropped from a height of 52 m.
The ball reaches the ground in 75 seconds
We need to find the average speed of the ball. The ball will travel a distance of 52 m in 75 s. The average speed of the ball is distance divided by time taken. So,
[tex]v=\dfrac{52\ m}{75\ s}\\\\v=0.69\ m/s[/tex]
Hence, the average speed of the ball is 0.69 m/s.

Answer:
you need to include the units for both axis to be able to answer this
Explanation:
average speed in uniform motion is the slope anywhere on the line but you could always pick 2 points and do it that way and speed is just rise over run
or y2-y1/x2-x1
Pick two points on the line and determine their coordinates.
Determine the difference in y-coordinates of these two points (rise).
Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
the second bit i think they are looking for this calculation y = mx + b, where m is the slope and b is the y-intercept (where the line crosses the y axis (the vertical one that has no units
Then use that formula for the last question and put in the x value of 10 and complete the formula to find out what y is

Answer:
If the fan speed increases, then the acceleration increases because a greater fan speed supplies more energy to move the cart.

How can positive feedback influence the stability of a system?
A. It can cause the system to remain stable as long as inputs are
constant
B. It can cause the system to oscillate between stability and
instability
c. It can cause instability that eventually results in the system's
destruction
D. It can cause instability by reversing the direction of the system,
The positive feedback influence the stability of a system is: It can cause the system to remain stable as long as inputs are constant. Hence, option (A) is correct.
What is stability ?A body's capacity to return to its initial static equilibrium after being slightly shifted is referred to as stability.
A body in equilibrium doesn't suffer linear acceleration or a turning effect, and unless a force from the outside disturbs it, it will stay in that state forever. (The First Law of Newton)
When tiny, externally induced displacements from an equilibrium result in forces or torques that tend to oppose the displacement and bring the body back to its initial equilibrium, the equilibrium is said to be stable.If even the smallest deviations result in forces or torques that tend to increase the displacement, the equilibrium is said to be unstable.Learn more about stability here:

A student walks to the right 25-m along the 800 hall in 15-s. They turn around and walk 15-m to the left in 8.0-s. Calculate the average speed and the average velocity
Answer:
Explanation:
Total distance covered = 25 + 15 = 40 m
Total time = 15 + 8 = 23 s
Average speed = total distance covered / total time
= 40 / 23
= 1.74 m / s
Total displacement = 25 - 15 = 10 m
Total time = 15 + 8 = 23 s
Average velocity = total displacement / total time
= 10 / 23
= .434 m / s to the right .
The average speed of the student is approximately 1.74 m/s, and the average velocity is approximately -1.74 m/s (to the left).
Given:
Distance to the right = 25 m
Time taken to the right = 15 s
Distance to the left = 15 m
Time is taken to the left = 8.0 s
To calculate the average speed and average velocity, we need to use the following formulas:
Average speed = Total distance traveled ÷ Total time taken
Average velocity = Displacement ÷ Total time taken
Calculate the total distance traveled:
Total distance = Distance to the right + Distance to the left
Total distance = 25 + 15 = 40 m
Calculate the total time taken:
Total time = Time taken to the right + Time taken to the left
Total time = 15 + 8.0 = 23 s
Calculate the average speed:
Average speed = Total distance ÷ Total time
Average speed = 40 ÷ 23 = 1.74 m/s
Calculate the displacement:
Displacement = Final position - Initial position
Displacement = (-15 ) - 25 = -40 m
Calculate the average velocity:
Average velocity = Displacement ÷ Total time
Average velocity = -40 ÷ 23 ≈ -1.74 m/s
So, the average speed of the student is approximately 1.74 m/s, and the average velocity is approximately -1.74 m/s (to the left). The negative sign in the average velocity indicates that the student's net direction is to the left.

In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.
