AP Kinematics Equations

An airplane accelerates down a runway from rest at 3.20 m/s² for 32.8 s until is finally lifts off the ground. Determine the distance traveled before takeoff.

Which equation is appropriate?

• vf=vi+a*t

• x=vi*t+1/2at²

• vf²=vi²+2aX

• x=((vf+vi)/2)t

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

Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds, then what is the distance that the sled travels?

Choose the appropriate equation.

• vf=vi+at

• x=vit+1/2at²

• vf²=vi²+2aX

• x=((vf+vi)/2)t
