The graph below shows the velocity V (t) of a particle A moving along the x-axis and can be defined by a continuous linear piecewise-defined function over the interval 0 t 9. (0,2) 3 (2,-2) s 5 9 9.- A} Over which time interval(s) does particle A move to the right? Over which time interval(s) is particle A slowing down? Justify your answers. B] Consider the velocity of particle B that moves along the x-axis to be Vg(t) = t- 4t + 3 defined for 0 t9. Over what interval(s) does particle B move to the left? Over what interval(s) is particle B's speed increasing? Justify your answers.
