Read your textbook, look at my weekly summary video and then look at these extra questions and problem solving videos.
Question: Two runners in a 100 m race start from the same place. Runner A starts as soon as the starting gun is fired and runs at a constant speed of 8.00 m/s. Runner B starts 2.00 s later and runs at a constant speed of 9.30 m/s.
a) who wins the race?
b) how far behind is the loser?
Here is the pdf solution of the problem solved in the video.
Here are two important "Check your understanding questions". I have written comments and feedbacks to your correct or incorrect answers but you won't see those until you try them. These questions are not graded but try them out for real. Many of them are good example questions that could be on the exam.
Page 14 in your book discusses the common sign confusions relating to acceleration and velocity. Be careful with the words speeding up and slowing down. Also be careful with speed vs velocity! These words have different physical meaning!
We will return to the 2 dimensional case in Chap 3. For the moment, we are only asking you to do addition and subtraction in one dimension.
The geometric arrow can be confusing. Here is a trick! Just replace the arrows with numbers. Vector A would be +4 while vector B would be -3.
What is A+B and what is A -B? Much easier with numbers right?
