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 number represents initial velocity?

• v₀ = 29m/s

• v₀ = 110m

• v₀ = 34m/s

• v₀ = ?

A car slows down from +32 m/s to +8 m/s in 4 s. The acceleration is 

• 6 m/s/s opposite the motion
• 2m/s/s in the direction of motion
• 8 m/s/s opposite the motion
