for that question the answer says that its not possible to jump 7.66 meters, and at a velocity of 12m/s directly up. But doesn't he just like a projectile not vertical, and a take off velocity of 12m/s is possible

in that same paper there are two statements we need to discuss and they were both misleading and incorrect. is this a trend now?

huh? I can't understand what you mean when you say "But doesn't he just like a projectile not vertical, and a take off velocity of 12m/s is possible"

rofl...ur statement is 'misleading'

yes thats the trend these days... kidding. im not too sure. i wouldnt rely on trends.

It doesn't matter, because horizontal and vertical components of velocity are independent p)

So yes, it may be possible for a human-projectile to achieve an overall initial velocity of greater than 12 metres per second (I'd imagine some long-jumpers achieve greater velocities), but it is only the initial vertical velocity that determines how long you stay in the air. (see the experiment how a projectile dropped straight down takes the same time to hit the ground as one that is also projected horizontally). And it is NOT possible for a human to achieve an initial VERTICAL velocity as would be required in that question.

What nosadness is talking about vs what the answers meant:

oh thankyou so much.

the successone give such irrelevant stuff at the end of the answer like "exegeration..."
