Unformatted text preview: on the vertical axis, showing your work clearly below. constant acceleration: x(t) = x + v t + 1/2 at 2 v(t) = v + at 2 Quiz 8 Rubric Problems 1&2: C(1.5)  correct R(1.25)  correct shape but upsidedown, shifted vertically, or used time intervals incorrectly. Q(1.0)  incorrect in 1s time interval W(1.0)  incorrect outside 1s interval E(0.5)  incorrect inside and outside interval Problem 3: C(1.5)  correct D(1.4)  incorrect direction R(1.4)  math error Q(1.25)  said vf=0 or vi=0, resulting in a=3 or 3 m/s^2 W(1.0)  said deltav=0, therefore a=0 E(.75)  used wrong equation or used the right equation incorrectly. T(.75)  incorrect (and nonzero) velocities. Answers varied. S(.75)  wrote relevant equations, unfinished Y(0.5)  unclear/unjustified/major conceptual error Z(0.0)  blank...
