Hi for this question, part b, i drew the graph like this:

However, the ans shows this

I don't understand how its in a parabolic shape...
we know that acceleration is a constant number, so when u integrate a constant number u get a function for straight line, so isn't this meant to be an straight line but with absolute value? (also it doesn't go through the x axis because they asked for speed, which doesn't have direction and so it stays above x- axis)
Any help would be appreciated!
