whats the weight and shape of the rock it depends on that >:(
Well the average terminal velocity ofr an average sized jumper is 120mph. I fall at 120mph and fall 10,000 feet in 45/50 seconds so I guess about 213 feet per second.
About 18.7736250 seconds assuming that air friction is zero. I used a graphing calculator.. I'm not sure about what the formula for figuring this out is.
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.
To determine how far a pebble falls in ten seconds, we can use the formula for the distance of free fall, which is (d = \frac{1}{2}gt^2), where (g) is the acceleration due to gravity (approximately 32 feet per second squared) and (t) is the time in seconds. Plugging in the values, we get (d = \frac{1}{2} \times 32 \times (10^2) = 1600) feet. Therefore, a pebble falls approximately 1,600 feet in ten seconds.
H = 1/2 G T2 = 1/2 (32.2) (1.5)2 = 36.23 feet
Ignoring air resistance, that would be about 145 feet.
If we assume the time it takes for the ball to stop is directly proportional to the height it is dropped from, we can set up a proportion based on the given information. From the given data, we have the ratio of time to height as 11/1 = 25/2. Therefore, if we continue this ratio, the time it would take to stop if dropped from 3 feet would be 55 seconds.

There are no seconds in feet. Feet is a unit of measurement while seconds is a unit of Time.
It went off within the minute.

2,377.44 seconds to travel 8,450 feet.
20 feet in 0,5 seconds ==> 40 feet per second 40 feet per second * 3 seconds = 120 feet
