First of all, it depends on how fast it was falling at the start of its fall. Also, it depends on the air resistance. Since you did not give any, let's say that air resistance is 0 and the velocity of the object when it started its fall is 0 Since the formula is d=v(0)*t+(1/2)9.8*t^2 d=(1/2)9.8*t^2 since the start speed was 0 (v(0) is starting speed) d = 4.9*t^2 replace D with what we know. 30,000 feet is 9,144 meters. So - t*t=9144/4.9 So the square of T =1866.122449 (rounded it) T = is the square root of 1866.122449 Finally, T = 43.198639 T is about 43.2 seconds So, it would take about 43.2 seconds

If they're not falling through air, then a bean and a battleship both fall 692 feetin 6.556 seconds. The weight of the object makes no difference.If the object IS falling through air, then in order to answer the question, we need toknow the object's shape, size, and volume, plus the temperature, humidity, density,and pressure of the air, at every altitude between the ground and 692 feet.

There would be 600 ft² in an object that measured 100 feet long by 6 feet wide.
Not enough information. The length of the shadow depends on the height of the object AND on the how high the Sun is in the sky.
