You take 10.0/12.0 and you will get your answer
Answer:
<em>The car's average acceleration is</em> .
Explanation:
<u>Constant Acceleration Motion</u>
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being vo the initial speed, a the constant acceleration, vf the final speed, and t the time, the following relation applies:
If we need to find the acceleration, we solve the above equation for a:
The car accelerates from rest (vo=0) to vf=70 m/s in t=7 seconds. Substitute the values into the formula:
The car's average acceleration is .
<u>Note</u>: The choices are not very clear, but the second choice seems to be the correct answer.
First times 1.6 with 3.0
4.8 *10^3*10^-6
Then use the product rule (x^a*x^b = a^(a+b)
4.8 * 10^-3
So the answer would be = 0.0048
