Answer:
It's constant everywhere in its trajectory.
Explanation:
the projectile was launched with an initial velocity, the only acceleration that is affecting the projectile's velocity is gravity.
The acceleration of gravity is practically equal everywhere on earth, so during its trajectory, we have to take into consideration only the acceleration because of gravity.
This is only correct because the projectile was launched with an initial velocity and it's not accelerating from rest and then falls.
The answer would be 5.6x10^5
Answer: (A) Gravitational force are proportional to the masses of the two objects.
Explanation:
When they are dropped at the same height, taking their mass into account, the feather will touch the ground last.
The correct answer is HYDROGEN
