You are standing still in a field with some $x$ and $y$ axes drawn on it$.($Of course you are standing at the origin.$)$ James runs by at a constant velocity of $(3\frac{m}{s})hat(i)+(4\frac{m}{s})hat(j),$ and at that same moment Cecelia bikes by at $10\frac{m}{s}$ in the positive $y$ direc. tion. She has her brakes on and is accelerating at $-(2\frac{m}{s^2})hat(j).$ At the moment they both pass you all of your stopwatches are set to $0.$

$($a$)$ Two seconds after she passes you, what are Cecelia's position, velocity, and acceleration in your reference frame?

$($b$)$ At that same moment, what are Cecelia's position, velocity, and acceleration in James' reference frame?
