depends on the mass of the stone, the shape of the stone, and the height dropped from. sorry dude.
(4 meters/second)(40 seconds) = 160 meters.
Because this is a free fall questions, the equation d=1/2gt² can be used. Gravity is a given, 9.8 m/s² and the time is your 15 seconds of free fall. d=1/2(9.8m/s²)(15s)²= 1,102.5m. To find feet multiply 3.28084 to answer because that is how many feet are in a meter.
seconds to hour = divide 3600 3600divided by 4=900 hrs d=SxT =45x900=40500km\hr
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.
78.46 meters (257.4 feet)
1,100 to 1,300 feet.
576 feet
It has been known since the 16th century that the mass of an object is irrelevant to how far it will fall. The main factor influencing the rate of fall is the shape of the object and, therefore, the air resistance (or buoyancy).
490 meters
depends on the mass of the stone, the shape of the stone, and the height dropped from. sorry dude.
about 137 meters
4 Seconds
The answer depends on:where it is falling (if on a space ship, the answer may be 0)the extent to which air resistance affects the fall.
(4 meters/second)(40 seconds) = 160 meters.
The duration of Fall Out Fall In is 480.0 seconds.
108 m/s
