The velocity of a car traveling in a straight line increases from 0 meters/second to 30 meters/second in 8 seconds. What is the average acceleration of the car?

Question

anonymous · Answer

Do you know how to find acceleration?

anonymous · Answer

The formula to find acceleration is as follows.

$$Acceleration (a) = Change \in Velocity/Time Interval= (v2 - v1) / (t1 - t2)$$

I am not sure I am in high school and ant gotta clue

anonymous · Answer

Here, let's look at an example.

anonymous · Answer

A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. 

To find the answer, subtract 18.5 from 46.1 to get 27.6. Then divide that by 2.47 to get 11.17 meters/second^2.

To find yours, simply plug in the numbers.

This would look like such.

anonymous · Answer

Since it's 0 m/s to 30 m/s in 8 seconds, you would want to write it like this.

anonymous · Answer

$$30 \div 8 = ? \div 8 = Acceleration.$$
