a car accelerates from 4 meters/second to 16 meters/second in 4 seconds. the car's acceleration is
meters/second^2

3m/s^2

Explanation:

The equation of motion is given by:

V=U +at where V is the final velocity, U is the initial velocity, a is the acceleration and t is the time for which the object underwent acceleration.

Solving for a gives a = 3m/s^2

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

the answer would be 32*f
