m Consider an object moving along a line with the given velocity v. Assume t is time measured in seconds and velocities have units of :. Complete parts a through c. 3. Determine when the motion is in the positive direction and when it is in the negative direction. b. Find the displacement over the given interval. c. Find the distance traveled over the given interval. v(t) = 2t2 2m + 42; [0.8] a. When is the motion in the positive direction? Select the correct choice below and, if necessary, ll in the answer box(es) to complete your choice. 0 A- For t-values that satisfy D. (Use a comma to separate answers as needed. Type your answers in interval notation.) O B.
