First law: A ball is stationary on the ground. It doesn't want to move, but eventually a person will come and kick it.
Second law: A car will never be constant it will have to stop then go . Objects take time to accelerate and also take time to decelerate.
Third law: If your sitting on a chair at a table, and you want to go, what do you do? Push against the table. The table will push back at you and hence, your chair moves. If this law wouldn't work then you would have to move the chair manually.
Average velocity is a vector unit (i.e. includes magnitude <em>and </em>direction) calculated by working out distance ÷ time:
80 metres ÷ 20 seconds = 4 metres/seconds (m/s)
Therefore, your final answer is C. 4 m/s south.
