- 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=vo+at
d=vot+1/2at2
v2=vo2+2aΔx
d=1/2(v+vo)t
- 2. Multiple ChoiceA boat travels 12.0 m while it reduces its velocity from 9.5 m/s to 5.5 m/s. What is the magnitude of the boat’s acceleration while it travels the 12.0 m?1.3 m/s22.5 m/s23.0 m/s27.5 m/s2

- 5. 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=vo+at
d=vot+1/2at2
v2=vo2+2aΔx
d=1/2(v+vo)t
- 6. Multiple Choice
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.
v=vo+at
d=vot+1/2at2
v2=vo2+2aΔx
d=1/2(v+vo)t
- 7. 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=vo+at
d=vot+1/2at2
v2=vo2+2aΔx
d=1/2(v+vo)t
