- 1. The position function for a moving object is r(t) = <7et-2 — t², t² - 3t, ½-½ >. Find the following: a. The value of t when the object has the position vector <3, -2, 1> (1) t b. The velocity and acceleration vectors at the t- value you found above. (4) c. The angle between the velocity and acceleration vectors you found above. Is the object speeding up or slowing down? (2)
