Abox is lowered using a rope. if the acceleration of the box, is 2.5 m/s2 (downward) and the tension in the rope is 31 n, what is the mass of the box (in kg)?

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 : )
