Suppose you had a feather, an orange, and a watermelon. which of the following describes how quickly each of the objects will fall without air resistance, relative to the other two?
a. all three objects will fall at the same rate.
b. the watermelon will fall faster than the other two.
c. the orange will fall the fastest, followed by the watermelon and then the feather.
d. the feather will fall faster than the orange, which will fall faster than the watermelon.

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 : )

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
