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 upside-down, 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 non-zero) velocities. Answers varied. S(.75) - wrote relevant equations, unfinished Y(0.5) - unclear/unjustified/major conceptual error Z(0.0) - blank...
