- 1. Multiple Choice
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?
v=vi+at
d=vit+1/2at2
vf2=vi2+2ad
- 2. Multiple Choice

- 7. Multiple Choice
A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car. Choose the appropriate equation.
v=vi+at
d=vit+1/2at2
vf2=vi2+2ad
- 8. Multiple Choice
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 is 0 m/s? Which equation would you use?
v=vi+at
d=vit+1/2at2
v2=vi2+2ad
- 9. Multiple Choice
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=vi+at
d=vit+1/2at2
vf2=vi2+2ad
