Explanation:
To do this exam it is important first to clarify all your doubts, if you have any, before starting the exam.
If there is a subject that you do not master 100%, it is good to consult a teacher, or see an explanation on the internet.
You should also bear in mind that there are 45 questions and that the time you have to take the exam is 105 minutes, so you could as a personal goal try to answer each question in two minutes.
If a question is difficult for you, it is best to go ahead and leave that question to answer at the end.
The answer is determined to be 331.3 m/s.
