Velocity = Displacment/Time
The Attempt at a Solution
Ok, so I thought this was straightforward at first, but I'm having my doubts. The position column, I filled out with the standard assumption the right and up are positive and left and down are negative. For displacement, I was a bit confused as to what it was asking, so I figured each situation started at a point and wanted the displacement for that point. By that logic I got the signs for displacement which happened to be the same as the signs of position. Finally for velocity, I first thought it was based on whether the object was speeding up or slowing down. But, I thought that shouldn't really matter for the sign of velocity, but for whether it is increasing or decreasing, which the question doesn't care about. I know velocity = displacement/time, and since time is always positive, the sign of velocity should be dependent on displacement. So I put the same signs from displacement into velocity.
PS, I don't have any background in physics, this is my summer assignment to which they gave no background and no textbook -.-
The fact that all the signs ended up the same still makes me worried that I am doing/did something wrong.
