A golf club exerts an average horizontal force of 1000 n on a 0. 045-kg golf ball that is initially at rest on the tee. The club is in contact with the ball for 0. 0018s. What is the speed of the ball just as it leaves the tee?.

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.

It would have to be c or d
