                        v= 20.0m/s

                       T= 15.0s

                     __________

                          x=?                              x=VT t= 150m

Nitella [24]

Answer:

I believe the answer would be true.

Explanation:

Personally, I believe the answer would be true. A personal mission statement is a way to reflect your purpose through writing. It shows how you want to live your life, and shows your personal overarching goals. The very point of creating a mission statement is to make it easier to see if your actions are in line with your core ambitions.

I hope this helps! It's my first time trying to answer a question.
