Multiple Choice

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?
