1) If the velocity of a particcle is zero, can its acceleration be zero? Explain.
2) Consider the floowing combinations of signs and values for velocity and accleration of a particle with respect to a one-dimensional x axis.
Velocity | Acceleration
I do not understand this at all! Please please please please help if you can with as much as you can. ANY help will be greatly appreciated because I have no idea what to do.
