A car is traveling to the right with a speed of 29​​m/s when the rider slams on the accelerator to pass another car. The car passes in 110 m with constant acceleration and reaches a speed of 34m/s. We want to find the acceleration of the car as it sped up. What equation should you choose?

• vf=vi+at

• x=vit+1/2at²

• vf²=vi²+2aX

• x=((vf+vi)/2)t

Choose the appropriate equation.

• vf=vi+at

• x=vit+1/2at²

• vf²=vi²+2aX

• x=((vf+vi)/2)t
