12. A student is planning an experiment to compare the acceleration of four objects with different masses when they are dropped from the same height in a vacuum chamber located on Earth.
A The student predicts that the object with the most mass will reach the ground the fastest. Is this
student's prediction correct or incorrect? (1 point)
The student is correct
The student is incorrect
Justify your response in one or two sentences. (1 point)

B. Write a procedure that the students can follow while conducting their experiment. Your procedure
should be sequential, account for accuracy and precision, and be easily replicable (4 points)

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
