Answer :
a ) The slowest and fastest object are object 2 and object 1 respectively
b ) In a vacuum chamber all objects will fall at the same time
c ) In normal conditions, a golf ball would land first.
a ) From the data taken from the table,
Object 1 lands after 1.1 s
Object 2 lands after 1.8 s
Object 3 lands after 1.3 s
Object 4 lands after 1.1 s
Eventhough object 1 and 4 land at same time, at 1 s mark object 4 has more height than object 1. So object 1 would land first
b ) If conducted in a vacuum chamber, there will be no air resistance,. So all the objects will fall at the same time.
c ) In normal conditions, there will be air resistance. So air resistance will be larger in the object with larger surface area. Feather has a larger surface area than a golf ball. So feather will fall slower than the golf ball.
Therefore,
a ) The slowest and fastest object are object 2 and object 1 respectively
b ) In a vacuum chamber all objects will fall at the same time
c ) In normal conditions, a golf ball would land first.
