Giving reason for the answer


So please do make sure that by the end of each and every question you do learn something new okay so guys let me tell you something because you don't know, now guys we are now moving to question 4.4 okay so the question says on impact the car access a force of magnitude f on the truck and experiences an acceleration of magnitude. 

Okay so that was a mini statement given over there okay so obviously you might find that upcoming questions might be based on that statement. For the last time on impact the car exits a force of magnitude f so as they collide that car exceeds a force of magnitude f on the track and experiences an acceleration of magnitude so the question says determine in terms of f the magnitude of the force that the truck exits on the car on impact.

Give a reason for the answer okay very much important ladies and gentlemen guys an answer to this question is based on newton's third law. I'm giving you a challenge, I'm giving you a homework ladies and gentlemen I won't give you these easy answers but instead I'm going to train you so ladies and gentlemen if this car is exiting a force of F on the truck. So that means the truck it's also exiting the same amount of force on the car. 

Why is it the case ladies and gentlemen is because of Newton's third law okay. Newton's a third law, so I'm giving you a challenge to go and read about newton's third law and check if this will make sense okay. If that car was exerting a force of magnitude 2f on the truck so that means even the truck is applying the same amount of force on the car okay very much important ladies and gentlemen this question is allocated two marks.

You get a mark for indicating the amount of force and again for the reason okay so ladies and gentlemen let's now move to question 4.4.2. Okay so let's check what the question says so now the question says let's see the question says let's see ladies and gentlemen the question says determine in terms of the acceleration, that the truck experiences on impact. 

Give a reason for the answer okay, very much important, so it's very much important that you fully understand what the question says determine. In terms of your answer should be in terms of okay very much important. Determine in terms of the acceleration that the truck experiences on impact and they say give a reason for your answer okay.
