            An ability to read such plots is essential part of studying and undesranding kinematics.

            You are given the plot of the velocity (the speed) as the function of time. 


(A)  the particle moves forward  at those values/intervals of time, where v(t) > 0. 


(B)  the particle moves backward at those values/intervals of time, where v(t) < 0. 


(C)  at the time moment when the speed becomes equal to zero (changes from positive to negative).


(D)  


(E)  the particle is slowing down at  4 <= t <= 7, where the plot v(t) has negative slope, but the particle still moves forward.


(F)  The acceleration is zero where the plot v(t) has zero slope, i.e. is horizontal.


(G)  4 units of length per unit of time in positive direction

     and  4 units of length per unit of time in negative direction (one single point on the time axis.


(H)  This last question you just ready to answer on your own.
