Using the kinematic equation below we can determine the distance traveled if t=2, a=7.4m/s^2. First we must determine the final velocity:

Now we will determine the distance traveled:

Therefore, the drag racer traveled 81.83 meters in 2 seconds.
A snow blower is more powerful because it's easier, and it moves large amounts of snow easily. Shoveling uses all of <em>your power.</em> It can be difficult and it takes a long time to get the snow off of your lawn.
Therefore, using a snow blower is more powerful than using a shovel.
I hope this helped!
Answer: your question is incomplete, however I want you to know that there are four ways to mitigate a risk, these are:
avoid, accept, reduce/control, or transfer. Whatever the risk in your question is, it will definitely fit into any of the aforemened risk strategies.
