4. The position (in meters} of an object in two dimensions is (t3 - 6t2 +9t +2, -t2 + 4t +3) 0s 5 {:1 4s. This is the same motion as before. a. Does the object begin its motion speeding up or slowing down? i). ls the object turning right or left? Your answer MUST include quantitative reasoning. c. Create an equation (you do not need to solve) that you can use to solve for that time at which the object is neither speeding up or slowing down. d. Find the radius of curvature for the object at I = 2s
