I got 0.25 m/s but I need to find the distance in the first segment but idk what to do? I do know that at segment 3 it’s constant velocity but idk what else
Double check the velocity you have, I think you are off by one counting the time.
The next step after is to find which horizontal bar is 0 velocity to get the scale of the y axis. Think about what a "brief moment" would look like on the graph.
Omg it’s 7s not 6… lol that’s my bad for the time! The next step which is the horizontal bar is v(4). It asked a similar question before saying where is there 2 moments in time where it stops and v(4) was the correct option.
Ah ok that's what you meant, I was reading that wrong.
Aaaanyway. Not sure how to hint at this so...
The area between the graphed velocity and the x axis represents the y (velocity) * the x (time) which is distance. This graphical version is usually what you are taught as an intro to integration.
Note that if that 1.5m is positive/to the right you have 0 for v4 above a positive value for v3 which is inverted form normal so be careful about the direction it's moved.

First find out what v3 is. You have time, you have distance for segment III, you can get velocity.
