Use the data table and compare your calculated predictions with the measured y positions. Record your results in the table below. Describe any notable differences. Make a hypothesis about any differences.

0.3 s-0.4 m-0.57 m

0.5 s-1.2 m-1.27 m

0.7 s-2.3 m-2.4 m

Explanation:

i think the answer is b

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
