An automobile moving at 20m/s slows to a stop in 6.5
seconds. find the acceration of the car.

-3.1 m/s²

Explanation:

Given data

We can determine the acceleration of the automobile using the following kinematic expression.

a = Δv / t

a = vf - v₀ / t

a = (0 m/s - 20 m/s) / 6.5 s

a = -3.1 m/s²

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
