H = 1/2 G T2
T2 = 2H/G
T = sqrt( 2H/G ) = sqrt( 160/9.8 ) = 4.039 seconds(rounded)
And if I may offer a suggestion . . . Next time you copy a question off a test or a
homework assignment, you can go ahead and drop the number '7' off the beginning.
That way, it won't be so obvious, and it won't show everybody how sneaky you are.

Drop a stone from the top of a high cliff identify the system wherein the net momentum is zero as t?
The system wherein the net momentum is zero at all times during the stone's fall is the stone itself. Momentum is a vector quantity, and the stone experiences an equal and opposite change in momentum at each instant due to the gravitational force. The external forces acting on the stone can be neglected in this case.

What happens if you fall?
It all depends on how high or low to the ground you are once you fall. For example, if you fall off of a bridge that is 600 ft high, you would die. If you fall off of a 30 ft building or so, you might come out with serious injuries. If it is about 1 or 2 ft, then you would be fine!

Does an object dropped from twice as high take twice the time to fall?
No. Objects falling on Earth in a vacuum fall at an increasing speed of 32 feet per second per second and the same object dropped from the higher level will be traveling faster during the second half of its fall, thereby it will take less than twice the time required to fall half the distance.
Why do they call the suicide bridge the suicide bridge?
Many cities have bridges called "suicide bridge"s by the locals. This may be due to reputation, if many have taken their own lives by jumping from it, or just because it is high enough to be a fatal fall.
