SOS HELP ME Question #2
Solve for the maximum height of each of the numbers from your chart.

AngleVyVy^2/(2*g)

25         6.3    2.02

30          7.5  2.87

45         10.65.73

50         11.56.75

65         13.69.44

70         14.110.1

Vy = vertical velocity = V sin theta

2 g H = Vy^2      since the final velocity is zero

H = Vy^2 / (2 * g)

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 : )
