I assume everyone has got a definition so ladies and gentlemen you need to make sure that you know these definitions by heart okay. Because you know you might be asked to provide that information so ladies and gentlemen let's now move to question 4.3. Calculate the velocity of the truck car system immediately after the collision and this question it's allocated six marks. Ladies and gentlemen it's a lot of marks but a lot of easy marks okay so ladies and gentlemen we are now on question 6.3 okay.
What does the question wants you to calculate ladies and gentlemen they want you to calculate the velocity. How does your final answer, how is it supposed to look like? Let us say very much important that you ask yourself this type of questions so they want you to calculate the velocity of the truck car system of the truck car system ladies and gentlemen. You know immediately after the collision so that means your final answer should be anything in meters per second.
Obviously you might need to give the direction, why because this is a scalar, no this is a vector quantity ladies and gentlemen. What does it mean, what is a vector quantity means it has a value and a direction okay so that means if you just give the value you might lose a mark for the direction very much important ladies and gentlemen. So obviously guys obviously the direction you must either have westwards or is towards very much important guys, very much important okay.
