Having trouble getting the formula for this question.(adsbygoogle = window.adsbygoogle || []).push({});

1. During a football games, Igor is 8.0m behind Brian and is running at 7.0m/s when Brian catches the ball and starts to accelerate away at 2.8m/s^2 at rest.

Will Igor catch Brian? If so, after how long?

How far down the field will Brian have run?

2. Involves 5 uniform acceleration equations.

3. d= (vi)(t) + 1/2(a)(t^2)

8.0m +(t)(7.0m/s)=d

8.0 + (t)(7.0m/s)=(vi)(t) + 1/2(a)(t^2)????

Getting the formula is really confusing me. I realize that Igor is 8.0m behind Brian but I get confused at that moment where I must insert that into the equation.
