[SOLVED] I really need help
I understand the very simple questions and all, but when the book throws all these extra things at me, I get so lost. You might've remembered my earlier post (my first one), so I'm back with a bit more.
I tried using a a=[tex]\frac{v_{2}-v_{1}}{t}[/tex] equation, but that wouldn't work. I also tried the d = v t equation, but that wouldn't work either. I'm assuming I still use Fnet = ma for this.
For you answers could you also tell me why that works? Thanks a lot
EDIT: Additionally, I just read the sticky, and if a mod feels that it should belong in the homework section, please feel free to move it; but it's not really homework, as I'm just studying for a test.

Code:
If it takes a human cannonball 1.5s to exit a 1.6m long cannon, what is the average net force acting on the performer if his mass is 65kg?
