69. The kinematic equation of motion of a point along a straight line (axis x) is given by x = A + Bt + Ct2 + Dt3, where B = 9 m / s; C = -6 m / s2; D = 1 m / s3. Determine the average velocity <υ> and the average acceleration of a material point in the time interval during which the point moves in the opposite direction of the original.
