OW! Not long enough!
It depends on the height of the building and also on the direction the object is thrown in (up, down etc.).
10 meters per second due to gravity
9.8
The instantaneous velocity at the maximum height is zero because the object momentarily stops moving before falling back down due to gravity.
If thrown horizontal from same height the faster object will travel farther horizontally, but time to fall is the same. If thrown straight up, the faster object will take longer to fall
To toss a ball straight up so that it takes 4.0 seconds to return to you, it must be thrown at a speed of 19.6 meters per second. This is because it will have a speed of zero at 2.0 seconds, therefore it must have a speed of 19.6 meters per second for gravity's 9.8 meters per second squared to slow it to zero in 2 seconds.
... and what is the question? The second ball should arrive at the floor a second after the first, both should have the same speed.
265
No. The range of the projectile thrown at 90 degrees is 0. It goes straight up and then straight down!
True. Both objects, when released from the same height, will experience the same gravitational acceleration regardless of their horizontal motion. Therefore, the object that is dropped will hit the ground at the same time as the object thrown horizontally, assuming no air resistance. However, the dropped object will fall straight down, while the thrown object will travel horizontally as it falls.
