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...
