()You are running a race against your friend and are traveling toward the west. At 1s, your velocity is 1m/s. At 3s, your velocity is 5m/s. Calculate your acceleration.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
