1. The problem statement, all variables and given/known data So its pretty much just Physics 20 Algebra intro my teacher assigned us this stuff and i can do it fine i just don't know what to do with the brackets. d = ( vi + vf / 2 )t Solve for t, then vf ( can't find any alt codes for small f with the v ) 2. Relevant equations 3. The attempt at a solution i assumed that after you times the t from the one side and move it to the other that the brackets would then be removed, but a classmate told me that the brackets act as its own variable.
