The motion map shows an object's position and velocity at given times.

how can the map be changed so it shows constant acceleration after the object changes direction?
o by adding vectors that are all the same length and placing them above the current top row of vectors
o by adding vectors that gradually increase in length and placing them above the current top row of vectors
o by adding vectors that are all the same length and placing them below the current bottom row of vectors

answer: i don't know the answer good luck

explanation:

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

can somebody give me the answer so i can graduate
