Question

if a leaf an exercise book and a coin are released from a height of 6 feet at the same time, which one of the two will ground first? explain the reason ​

Answer 1

Answer:

An exercise book will hit thr ground first because it's mass is more than others then the coin will hit the ground as its density is more than the leaf bad thereafter the leaf will hit the ground.

Explanation:

This is because of following reasons -

1.The higher the mass and density, the more gravitational force will act on it. That's why first exercise book then coin and then leaf will hit the ground.

2. Wide contact with air things will fall at last, that is why the leaf which is in horizontal shape contact more with air and fall at last.

hope it helps..

please give thanks..

Answer 2

Both the exercise book and the coin will hit the ground at the same time.

Explanation:

• The formula of the time taken by the  object to hit the ground is equal to, ✓ (2S/a)

• Where we is the final velocity of the body. This is considering that both the body wear at initial velocity of zero when it is made to fall.

• Hence the  time taken by the body to reach the bottom is dependent only on the height and the acceleration due to gravity. The acceleration due to gravity is irrespective of the mass of the body. both the bodies will fall on the ground at the same time
