d = 16t²
t = 1 s
→ d = 16 × 1² = 16 × 1 = 16 ft
It will fall 16 feet.
Shorter wavelength = more energy. The farther the electron falls, the more energy that will be emitted.
The acceleration of gravity is 9.8 meters (32.2 ft) per second2.Neglecting air resistance . . .After 8 seconds, the speed is (9.8 x 8) = 78.4 meters per second. (rounded)After 8 seconds, the speed is (32.2 x 8) = 257.6 feet per second. (rounded)
A falling stone will increase in speed until it reaches it's terminal velocity, the speed when the downward force of gravity equals the upward force of drag, which causes the net force on the stone to equal zero, thus achieving an acceleration of zero. If atmosphere is ignored, a falling body will accelerate at 32ft/s (9.75m/s). The distance traveled in the first second would be 16 feet (4.87m), in the second second: 48 feet (14.63m) and in the third second: 80 feet (24.38m); hence after three seconds an object would have fallen 144 feet (43.89 meters) and is traveling at 96ft/s (29.26m/s).
If G = 10, then the body's speed is 10 at the end of 1 second,and 20 at the end of 2 seconds.During that interval of time, its average speed is (20 + 10)/2 = 15 m/s.The distance is (average speed) x (time) = 15 meters.
In order to come up with an answer, we have to impose a couple of rules: 1). we're trying this on the earth 2). we're ignoring the effects of air 3). it's not moving at the beginning of the 5 seconds ... that's when you drop it from your hand Then the rock falls 400 ft in five seconds. What's really interesting is that it doesn't matter how much it weighs. ALL rocks fall the same distance in 5 seconds.
A stone falls freely from rest The total distance covered by it in the last second of its motion equals the distance covered by it in the first three seconds How long does the stone remain in air?
The time required for a stone to fall from a given height can be calculated mathematically. Time equals the square root of two times the distance divided by force of gravity. Time is in seconds, distance in meters, and the force of gravity on Earth is 9.8 meters/second ^2.
A stone that falls from a ledge and takes 8 second to hit the ground travels a distance of 313.6 meters. You can find this answer by substituting 8 seconds for time in the physics formula d = 1/2 x acceleration x (t squared), where d = distance, acceleration is given as a =9.8 meters/second squared, and t squared is time in seconds.
No. Since the speed of a falling object keeps increasing, it falls through more distance in each second than it did in the second before.
ANSWER: a larger distance than in the second before
The distance from Niagara Falls, Ontario, Canada, to Philadelphia, Pennsylvania, is 296 air miles. That equals 476 kilometers or 257 nautical miles.
The air distance from Sydney, Australia, to Great Falls, Montana, is 8,211 miles. that equals 13,214 kilometers or 7,135 nautical miles.
The distance from Athens, Greece, to Niagara Falls, Ontario, Canada, is 5,053 air miles. That equals 8,131 kilometers or 4,390 nautical miles.
No. When the ball falls, there are two forces acting on it; one is the gravitational force and the other air resistance, which is dependant on speed. At the point it is released. Its instantaneous speed is 0m/s The next second, 10m/s, (result of acceleration). the ball will undergo decreasing acceleration. Thus the distance it falls each second is different.
If an object is dropped from rest at a height of 128 m, the distance it falls during its final second in the air is still 128 m.
At G = 32.17 feet/second2, the distance you fall in 3.5 seconds is 197 feet. (1/2 A T2)
speed x time = distance convert miles per hour to miles per second speed = 175 miles per hour divided by 3600 seconds per hour distance = 175/3600 times 30 seconds = 1.46 miles
