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