Question 9.Do the math Calculate the average acceleration of the rock in the diagram using this question

Please Help!! Been stuck on question sorry if it’s blurry

Answer 1

9.8 m/s²

Step-by-step explanation:

Fill in the blanks with the numbers from the diagram.

`\text{average acceleration}=\frac{\text{final velocity - initial velocity}}{\text{time it takes to change velocity}}\\\\\text{average acceleration}=\frac{39.2\text{ m/s}-9.8\text{ m/s}}{3\text{ s}}=(29.4)/(3)\text{ m/s$^2$}\\\\\boxed{\text{average acceleration}=9.8\text{ m/s$^2$}}`

You are told to start with t = 1 second and end at t = 4 seconds, so the elapsed time for which you're computing the acceleration is 4-1 = 3 seconds.

When you fill in your blanks, you probably want to put numbers only. I like to show the units in physics problems, just to make sure the math is right.
