1) Starting from rest, a particle travels along the x axis with a constant acceleration of +3.0 m/s2. At a time 3.7 s following its start, it is at x = -102 m. At a time 6.6 s later it has a velocity of +30.9 m/s. Find its position at this later time. 2) A rock dropped from a cliff covers one-third of its total distance to the ground in the last second of its fall. Air resistance is negligible....
