Math brain buster?

Question

Tow idenical cannons are aimed at each other, ir shells fired simutanously at exactly the same speeds. Ignoring wind resistance for a moment, will hey hi or miss?

Answer 1

Gravity will pull both connonballs to the ground. So they will not hit each other.

Answer 2

That really depends on how far apart the cannons are, how high the cannons are, and how fast the shells are moving when they're initially fired. Unless there's some clever trick I'm missing here, I don't think you have enough information to answer this question.

Answer 3

how is this a math brain buster? For one thing, how far apart are the cannons? How much else are we ignoring? Are we ignoring the fact that the two cannons probably have different surface roughness in the barrel?

The only thing busting my brain is how vague this question is!

Answer 4

if the 2 cannons are at different heights, they can hit each other, because the paths of the cannonballs are not symmetrical.

if they are at the same height, the paths of the cannonballs will be symmetrical and the cannonballs will hit each other in the middle.

Answer 5

enable the form be abcd. a million. the 1st digit is one-third of the third digit. 1b3d 2b6d 3b9d 2. The fourth digit is two circumstances the 2d digit. a1c2 a2c4 a3c6 a4c8 3. the 1st digit and the third digit upload as much as two times the sum of the 2d digit and fourth digit. including first and third 1b3d = 4 2b6d = 8 3b9d = 12 two times the sum of 2d and 4th. a1c2 = 6 a2c4 =12 a3c6 =18 a4c8 = 24 3924

Answer 6

Where there trajectory curves co-inside!

Answer 7

they'd miss...right?
