You've already chosen the best response. It's a vector because acceleration has both a direction and a magnitude. An example would be a car stopping at a rate of 10 m/s. In this example the direction of acceleration is opposite the direction of velocity (towards the trunk) and the magnitude is 10 m/s.Show full answer.ou've already chosen the best response.
