Question

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

....Please Help!!​

Answer 1

Required AnswèR :

៚9.8 m/s²

☆Explanation:

Fill in the blanks with the numbers from the diagram.

$\sf\blue{\text{Average acceleration}}\\=\dfrac{\text{Final - Initial velocity}}{\text{time it takes to change velocity}}$

$\sf=\dfrac{39.2 m/s-9.8 m/s}{3s}$

$\sf{=}\dfrac{29.4m/s}{3m/s}$

$\sf\boxed{\text{Average acceleration}=9.8\text{ m/s ^2 }}$

______________

We 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.
