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 29m/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

If Michael Jordan has a vertical leap of 1.29 m, then what is his takeoff speed if his acceleration is -9.8 m/s2 and his velocity at the top of his leap i 0 m/s?
vf=vi+at
d=vit+1/2at2
vf2=vi2+2ad
d=1/2(vf+vi)t
A ball is dropped from a building. How fast is it traveling after falling for 1.77 s? (Hint: It's a free falling object)

17.35 m/s
18.91 m/s
20.03 m/s
If Michael Jordan has a vertical leap of 1.29 m, then what is his takeoff speed if his acceleration is -9.8 m/s2 and his velocity at the top of his leap i 0 m/s?
v=vo+at
d=vot+1/2at2
v2=vo2+2ad
d=1/2(v+vo)t
An engineer is designing the runway for an airport. Of the planes that will use the airport, the lowest acceleration rate is likely to be 3 m/s2. The takeoff speed for this plane will be 65 m/s. All airplanes will start from rest. Assuming this minimum acceleration, what is the minimum allowed length for the runway?
v=vo+at
d=vot+1/2at2
v2=vo2+2ad
d=1/2(v+vo)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?

x=vit+1/2at2
vf2=vi2+2aX
x=((vf+vi)/2)t
