Science lovers ! what do the lines making a circle around the low-pressure area indicate? a. an occluded front b. areas of equal altitude c. areas of equal pressure d. a stationary front what kind of weather will the low-pressure system bring to chicago on day 3? a cold and rainy b warm and sunny c cold and dry d warm and rainy i dont have the pictures! they werent allowing me to copy and paste or save the pages or pictures! im really sorry!

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
