A 1,000 kg truck moving at 10 m/s runs into a concrete wall. It takes 0. 5 seconds for the truck to completely stop. What is the magnitude of force exerted on the truck during the collision?.

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's.
