s = 1/2*g*t2 where g is the acceleration due to gravity which, on the surface of the earth is approximately 9.8 metres/second2
So t = 4 gives s = 1/2*9.8*42 = 78.4 metres.
A rock falls off a bridge and hits the water 8 seconds later. How high is the bridge? A rock falls off a bridge and hits the water 8 seconds later. How high is the bridge?
Monopole is an antenna with just the radiating element where the ground of the transmitter is connected to an electrical ground which serves as an Image ground to the radiating element. Thus the name "mono" pole. Dipole is where the ground and the radiating elements are connected to two different elements where one is the radiating element and the other is the ground to the later. Thus the name "Di" Pole Cheers by zafran khan
The white settlers on the Great Plains were accustomed to building houses with wood. There was not enough wood on the Plains to build a house. Later when rail transportation was built wood could be brought in on trains.
It was sold a year later for about 1.6 million. 14 months later it was listed for sale at high 1.3 million but as of June 2011, it is listed at $925,000. Taxes have dropped down to about 10K a year. It's a steal at that price!
Andy Sixx went to Oak Hills High School but later dropped out. My brother was 2 years ahead of him at Oak Hills. Whether he went to the school of creative and performing arts later, i dont really know.
a. 144 feet b. 96 ft/sec.
44 meters tall
176.4 meters
.. You need the height of the building to figure it out..?
Disregarding air resistance, what is the speed of a ball dropped from 12 feet just before it hits the ground? (Use 1 ft = 0.30 m, and use g = 9.8 m/s2.)
If it was thrown horizontally or dropped, and hit the ground 3.03 seconds later, then it hit the ground moving at a speed of 29.694 meters (97.42-ft) per second. If it was tossed at any angle not horizontal, and hit the ground 3.03 seconds later, we need to know the direction it was launched, in order to calculate the speed with which it hit the ground.
It went off within the minute.
Yes.
28.224m
If the ball was dropped from a roof and hit the ground 3.03 seconds later, then when it hit the groundits velocity was 29.694 meters (97.42 feet) per second (rounded) downward.
Diving is generally taken to mean that you start from rest and jump. If Superboy dives off the building, he would initially have had zero velocity, relative to the building.
As , s = ut + 1/2 a t2 , since a ball is dropped , the equation is modified as h = ut + 1/2 g t2 Therefore , h = 0 x t + 1/2 x 9.8 x 22 [ u = 0 ,since the ball is at rest] h = 19.6 meters Height of the window = 19.6 meters
