Answer:
average speed is 0.159 m/s
average velocity = 0.0011 m/s
Explanation:
given data
time = 41.6 s
total distance = 6.65 m
length = 0.0463 m
to find out
average speed and the magnitude average velocity
solution
we know average speed formula is
average speed = 
...............1
put here value
average speed = 
average speed is 0.159 m/s
and
average velocity formula is
average velocity = 
...............2
here displacement is initial point to final point and here is 0.0463 m
put here value
average velocity = 
average velocity = 0.0011 m/s
The magnitude of the acceleration of the elevator is 90m/s^2
Due to Newton's Law ∑ Forces in direction of motion is equal to mass
multiplied by the acceleration
We have here two forces 5000 N in direction of motion and the weight of the person in opposite direction of motion
The weight of the person is his mass multiplied by the acceleration of gravity
So ,
W = mg , where m is the mass and g is the acceleration of gravity
m = 50 kg and g = 9.8 m/s²
Substitute these values in the rule above
W = 50 × 9.8 = 490 N
The scale reads 5000 N
F = 5000 N , W = 490 N , m = 50kg
F - W = ma
5000 - 490 = 50 a
4510 = 50 a
Divide both sides by 50
a = 90.2 m/s²
Hence the acceleration is 90m/s^2

Is it just me or can anyone else not see a graph? (Because I can’t)
It's a combination of all those things. probably because we are taught from an early age to write in an academic fashion, giving balanced arguments and a conclusion. When speaking from the heart, there is no opposing argument nor is there a conclusion, just emotion.
