What is the initial velocity in the problem below: "A car traveling initially at 7.0 m/s accelerates to velocity of 12.0 m/s in 2.0 s. What is the average acceleration of the car?

Explanation:

Given that,

Initial velocity, u = 7 m/s

Final velocity, v = 12 m/s

Time, t = 2 s

We need to find the average acceleration of the car. The acceleration of an object is equal to the rate of change of its velocity. It can be given by :

So, the acceleration of the car is .

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
