The graph indicates Linda’s walk. Which best describes the graph?

Linda started out moving, and then stopped moving after 6 seconds.
Linda started moving away from the start point, and then moved closer.
Linda never moved the entire trip.
Linda’s path results in a negative slope.

Linda started moving out and then stopped moving after 6 seconds

Explanation:

On the axes of the graph, one can see that the lower axis is labeled (time). Time can only move forward, thus the graph will forever continue leftwards.

The verticle axis is labeled (Position in (m)), this changes relative to the motion that Linda takes. As one can see, from (0) to (6) seconds Linda was moving forward, as her position in meters was increasing. however, at 6 seconds she stopped moving, thus the graph remained a horizontal line. Therefore, the answer is the following:

Linda started moving out and then stopped moving after 6 seconds.

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
