Could you please help out? Anyone?
Aaand, I also have trouble with question number 13 here, yeah.

velcity time graph:
1) if its a horizontal straight line = displacement is a straight steeping upwards line
2)if its a straight steeping line = displacement is a curve
3) if object is falling down= velocity increases= displacement time graph has a slope
slope=velocity
as velocity increases, slope must increase also and viceversa
got it?
