Question 3) The diagram is about the motion of an object in the xy plane: Overall the object starts at point A on the +y axis, moves in the-y direction until reaching the origin of coordinates where it makes a right angle turn and moves in the +x direction until reaching point D on the x-axis. The speed is not constant and we know more detail about the motion at only four points: When t-0.00s] it is at point A...
