Three objects were dropped from the same height. Assume they are in free fall.

$($Object A: Mass $5kg,5cm$ long$)$

$($Object B: mass $10$kg$,10cm$ long

$($Object C: mass $15$kg$,15cm$ long

In which order do they hit the ground?

In a vacuum, which object has a greater acceleration in freefall: A sandwich or a piano?

A$)$ The sandwich

B$)$ The piano

C$)$ Depends on which has more air resistance

D$)$ Both objects have the same acceleration
