Auto Acceleration Problem: 40 m/s to 8 m/s in 200 m

  • Thread starter androcci
  • Start date
In summary, auto acceleration is the change in velocity of a moving object over time, calculated by dividing the change in velocity by the change in time. It is the measure of how quickly an object is speeding up or slowing down. There is a limit to how fast an object can accelerate, determined by its mass and the amount of force applied. Acceleration refers to an increase in velocity, while deceleration refers to a decrease in velocity. These changes in speed have an impact on the overall distance traveled by an object, with a longer acceleration or deceleration period resulting in a greater distance traveled. In the given problem, the object would travel a total of 204 meters during the acceleration period.

An automobile moving along a straight track changes its velocity from 40 m/s to 8 m/s in a distance of 200 m.

ok this is a practice test and i have the answer keys for this. but if anyone could help me here. thanks!

welcome to pf!

hi androcci! welcome to pf! :wink:

use one of the standard constant acceleration equations

show us what you get :smile:

1. What is the definition of auto acceleration?

Auto acceleration is the change in velocity of a moving object over time. It is a measure of how quickly an object is speeding up or slowing down.

2. How is auto acceleration calculated?

Auto acceleration is calculated by dividing the change in velocity by the change in time. In the case of the given problem, the acceleration would be (40 m/s - 8 m/s) / (200 m) = 0.16 m/s2.

3. What is the difference between acceleration and deceleration?

Acceleration refers to an increase in velocity, while deceleration refers to a decrease in velocity. Both terms describe changes in an object's speed, but in opposite directions.

4. Is there a limit to how fast an object can accelerate?

Yes, there is a limit to how fast an object can accelerate. This limit is determined by the object's mass and the amount of force being applied to it. The greater the mass and force, the slower the acceleration will be.

5. How does auto acceleration affect the overall distance traveled by an object?

Auto acceleration can have a significant impact on the distance traveled by an object. The longer the acceleration or deceleration period, the greater the distance traveled. In the given problem, the object would travel a total of 204 meters (200 m + 4 m) during the acceleration period.
