D. I, II, III and IV
- acceleration is define as a rate of change of velocity with respect to time, meaning once you move and get to another direction (fast or slow) it means you're accelerating.
I - a truck is changing directions which means he's applying speed to get his final velocity by changing directions
II - a car accumulating a large amount of speed, which 'cause a rate of change in velocity.
III - a moving motorcycle stops, also defining the rate of change in terms of speed/velocity, by slowing down.
IV - a rolling ball moving. from the word "moving" itself it creates a rate of change in something, maybe due to gravity or constant.
