01e - The Kinematic Equations

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?

• v=v_o+at
• Δx=v_ot+1/2at²
• v²=v_o²+2aΔX
• Δx=((v+v_o)/2)t

Which equation is appropriate?

• v=v_o+at
• Δx=v_ot+1/2at²
• v²=v_o²+2aΔX
• Δx=((v+v_o)/2)t

An object with an initial velocity of 3.50 m/s moves east along a straight and level path. The object then undergoes a constant acceleration of 1.80 m/s² east for a period of 5.00 s. How far does the object move while it is accelerating?

• 6.30 m
• 17.5 m
• 27.2 m
• 40.0 m
