- 1. Multiple Choice
An airplane accelerates down a runway 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+at
Δx=vit+1/2at2
vf2=vi2+2aΔX
Δx=((vf+vi)/2)t
- 2. Multiple ChoiceWhen a car goes around a corner at 20 mph, why do we say it accelerates?The car is accelerating because of the velocity is constantThe car accelerates because it's going 20 mphCars always accelerate when they are in motionThe car is accelerating because it's changing direction
