Question
(AYK-2 modified) Two identical stones are thrown from the top of a building, both with and then again without air resistance. Stone 1 is thrown straight up, and stone 2 is thrown straight down with the same initial speed as stone 1. Which of the following statements are true (select all which apply)? without air resistance, stone I will hit the ground with a faster speed than stone 2 when it hits the ground. without air resistance, stone I will hit the ground with a slower speed than stone 2 when it hits the ground. without air resistance, stone I will hit the ground with the same speed as stone 2 when it hits the ground with air resistance, stone I will hit the ground with a faster speed than stone 2 when it hits the ground with air resistance, stone 1 will hit the ground with a slower speed than stone 2 when it hits the ground with air resistance, stone 1 will hit the ground at the same speed as stone 2 when it hits the ground It is impossible to determine which stone will have the faster speed upon hitting the ground if air resistance is involved.Explanation / Answer
with out air resistance both the stones will hit the ground at the same speed because even one stone is thrown upwards while it reaches to its starting postion it has same speed hence both will reach simultaneously.
but in the air resistance the first stone will hit the ground with lower speed than second because it is also suffering air resistance during travel to reach its intial position hence
option 3 and 5 are correct.
