You push a cart with mass 30 kg forward, giving it an acceleration of 5 m/s2. How much force did you apply?
\[\sum_{}^{}F=ma\] \[M = 30kg\] \[A = 5 m/s^2\]
I would suggest that before you try problems you should look at all the equations in the chapter one by one and try and think about what they really mean and whats going on. What are the units? What are the restrictions? Come up with an imaginary situation as to why you would use it. It is time consuming but really worth it. Physics is really hard for most people and it is going to get way worse than F=ma. DRAW PICTURES! https://www.youtube.com/user/ilectureonline or https://www.khanacademy.org/ are amazing resources.
the drawing of ur problem is as below
