1.At time t = 0, the initial position of an object is x1 = -9.00 m....

1.At time t = 0, the initial position of an object is x1 = -9.00 m. Two seconds later he is in position

x2 = 5.00m and finally moves to position x3 = -12.0m for a total time of three seconds. Speed

average (in m / s) of the object in this time interval is:

2.The position of a particle is described by the function x = 4.0 t2 - 2.0 t + 2.0 (m). Determine the average acceleration (in m / s2) for the time interval t1 = 1.0 s and t2 = 3.0 s.
