16) Bob is on his bike and is slowing down, he is moving in the negative x direction, what direction is Bob's acceleration? (Be careful Canvas my not have the same order for the answers) Bob +x There is no acceleration he is slowing down There is no acceleration because there is no change in velocity 17) A bird flies at a constant velocity between two positions indicated by the position vectors below, if the bird flies from the initial...
