At time t = 0 s, an object is observed at x = 0 m; and its position along the x axis follows this expression: x = -4t + t2, where the units for distance and time are meters and seconds, respectively. What is the object's displacement ?x between t = 1.0 s and t = 3.0 s? A +10 m B +2 m с -5 m D -21 m E +16 m
