# Bye Brilliant

Will meet you after my 12th exams ------>14/03/14

Departing with a simple question

I have two identical pistols. I decided to do a simple experiment with it.

i reached the top of my building loaded one pistol with a bullet of mass "m" and loaded the other bullet with mass "7.5m" pointed both the gun towards the ground (bringing both the guns to the same level) and pulled the triggers at the same time

WHICH OF THE BULLET WILL REACH THE GROUND FIRST?

1.BULLET A (mass-m)

2.BULLET B(mass-7.5m)

3.Both of them because gravity acts equally on them

4.Information is not sufficient to give the answer

After answering think about what will happen if both are shot horizontally from the top of the building??

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Oh, when I commented, he hadn't posted any question, it just said "will meet you after 12th exam".

1. The bullet with mass m hits the ground first.

1. The one that's heavier takes more work to go the same speed as the one that's lighter ($F=ma$). Therefore, the gun loaded with the smaller bullet will travel much faster and hit the ground first.

Ignoring air resistance, option 1 is correct because the lighter bullet will get some initial acceleration from the pistol. Then only gravity does the rest. But the heavier bullet will get a lesser acceleration because of more inertia.

With air resistance and all sort of other things, option 2 is correct. Because it has more inertia, it falls first. If there's wind, the lighter bullet gets carried away and again the heavy bullet touches the ground first.
