The starting velocity was 0 m/s, and the final velocity was -15.35 m/s. Based on this, what was the average

velocity of the rock? In general, to find the average of

any 2 things, you add them together and divide by how

many things there are.

The average velocity is -7.675 m/s

Explanation:

Given;

initial velocity, u = 0 m/s

final velocity, v = -15.35 m/s

Based on the follow up state " In general, to find the average of any 2 things, you add them together and divide by how many things there are", the average velocity will be calculate as ;

Sum of the velocities = 0 m/s + (-15.35 m/s) = -15.35 m/s

Number of velocites = 2

AVERAGE VELOCITY = (-15.35 m/s) / (2)

AVERAGE VELOCITY = -7.675 m/s

a. carbon monoxide from car exhaust

b.particulate matter, such as soot

c.water vapor from a factory smokestack

d.acid rain

these are the answer choices im on that question right now

tbh i don't know the answer for this question
