No, they fall at the same time.
When you hit the ground. While they are falling they are in the air, and falling in and of itself will not kill you. The impact will always kill you -- unless you have a heart attack during the fall.
You need the amount of time that it took to fall the 45m.
When you say "time of fall", I'm going to assume you mean "time of hitting the ground".The kinetic energy it has when it hits the ground is exactly the potential energyit had on the roof. (As is our tradition, we're ignoring air resistance.)Potential energy = (mass) x (gravity) x (height)5,000 = (20) x (9.8) x (Height)Height = 5,000 / (20 x 9.8) = 25.51 meters
39 m\s downward
There are theories that many people, particularly those with a bad heart, die before hitting the ground due to the shock and terror of the fall itself, although this is really difficult to determine since it is impossible to predecit the exact second a person dies (whether they die just before impact from a heart attack, or the impact itself).
It will fall with increasing velocity due to gravity and reach the peak velocity just before hitting the ground.
why do the blooms fall from the trees before they ripen & fall to the ground? please forward answer to www.fslawson@win.org thank you
Get a parachute
Yes
No, they fall at the same time.
The answer depends on its initial velocity and the height from which its fall to the ground is measured.
It will fall before the Doomsday come,
When you hit the ground. While they are falling they are in the air, and falling in and of itself will not kill you. The impact will always kill you -- unless you have a heart attack during the fall.
if you do it right before the ground you will die, but if you have the game it is not that hard to test
Not unless you fall into tall, soft trees to slow you before you hit the ground.
You need the amount of time that it took to fall the 45m.
