Answer:
The literary production of the 16th century is of paramount importance for history, philosophy and literature, as it is through it that we can analyze the reports of what Brazil and its people were like in that period, even if seen by European man with customs and realities different from ours.
The acceleration is zero.
Acceleration is by definition the change in velocity per unit time.
If the velocity of the girl is uniform at 1.5 m/s, then there is no acceleration.
Remember that velocity is a vector quantity and a vector can change in 3 ways
Magnitude only
Direction only
Both magnitude and direction.
Now the magnitude of velocity (speed) can stay constant while the direction is changing. This is the case in circular motion.
In the question above, it is mentioned that the girl is moving along a straight road. Therefore no change in direction of velocity.
Final Answer: No acceleration because of no change in velocity.
I'll use me and one of my sisters as an example if that's okay. (also, I only have . between every word my sister says because she talks really fast.)
Me: "Why are you so upset?"
Sister: "I'M.NOT!.LEAVE.ME.ALONE!"
Me: "Come now, and tell me, or do I have to get Mammaw?"
Sister: "No.I.Don't.Want.To.Tell.You.I.Said.Leave.Me.Alone!"
Me: "What ever. Eventually, I'll find out."
Basically, or at least in my adopted family, the females like to yell when they're upset or angered, and when they're in a good mood, they talk as if they never yelled in their life. I know it's not the same for all females, because I don't do it and I have friends who don't do it.
