Assertion : If a particle is thrown upwards, then distance...

Assertion is false: The distance covered by a body thrown vertically upwards in the last second of its upward journey is independent of its initial speed. This is false. The distance covered in the last second depends on the speed at which it passes through that second. For example, if it's thrown very fast, it might cover more distance in the last second before reaching its peak than if thrown slowly. More accurately, the distance covered in the first second of free fall (or the last second of upward motion assuming symmetry and starting/ending at (\mathrm{v}=0)) is independent of initial speed. Reason is true: For a freely falling body, the distance covered in successive seconds is in the ratio 1:3:5:... This is a property of motion under constant acceleration (g) starting from rest.
