If two different sized objects have the same density, what can you conclude about the object?

Short YES

Long

Density is generally regardless of how big or small a substance is and is neither dependant on its shape. A statue made of gold and a brick made of gold might have different masses and volume but they have same density.

By universal definition, density of a substance is the mass per unit volume.

D = Mass/Volume

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
