A 750 kg car going 15 m/s hits a 675 kg car going 10 m/s. After the collision, the 750 kg car moves at 6.5 m/s. What is the velocity of the 675 kg car after collision?

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 : )
