i know its

Vfinal=Vinitial+acceleration*time but i dont know what 5.00 m/s2 (squared) means...

would it be 30.0 = 20.0 + 5.00 m/s^2 (squared) * time, but i have to solve for time..... whats the squared for....? can you write me this equation in numbers so i can just slove it, because i know how it goes just the squared confuses me....

**drwls**, Tuesday, September 11, 2007 at 8:58pm5.00 m/s^2 is the acceleration rate of the passing car. Multiply it by the time interval for the velocity change/ You havew already written the correct equation. Solve if for t.

t = (10 m/s)/(5 m/s^2)

Your answer will be in seconds
