A projectile is spotted at 83 m above ground, travelling at 11 m/s [down]. How long
will it remain in the air? Assuming it was launched from the ground, how long had
it been in the air when it was spotted?
My advice would be to duck
At least you said please. But alas you still cheat.
You don't have time to dig. You barely have time to bend over and kiss your ass goodbye.
Without additional acceleration from gravity you have less than 8 seconds. Gravity adds 32 ft (roughly 10 meters) per second per second to its velocity. Good luck.
I think you should send this question to Biden.
He’s talking Armageddon!
He’s buying anti- radiation sickness pills.
Buy plenty of duck tape and plastic sheeting just in case!
