Ok i am just moving around variables and the book got a result i cannot understand. I have v = Vo + a*t I want to solve for t so i first moved the v over Giving me 0 = Vo-V + a* t Then i want to divide by t giving t = Vo-V + a Right ???? the book has .....V - Vo t= ------ ..... a How did they get the a on bottom ? What step am i missing/not understanding ?
