P 2 - Sketch the velocity (vertical axis) vs. time (horizontal axis) graph for each of the following situations when an object: t t moving in the positive direction is at rest(v=0) with a constant speed (+v) t t moving in the positive direction with a constant speed greater than above accelerating in the positive direction starting at rest (+a) t moving in the negative direction with a constant speed (-v) t moving in the negative direction with a constant speed greater than above
