Question

the velocity of a falling object can be found using the formula v^3=64h, where v is the velocity (in ft per second) and h is the distance the object has already fallen. What is the velocity of the object after a 10-ft fall? How much does the velocity increase if the objects falls 20 ft rather than 10?

Answer 1

v^3? you sure that isnt v^2?

Answer 2

yeah your right, its v^2

Answer 3

im a mind reader lol

Answer 4

it was either that or we were moving into the fourth dimension ;)

Answer 5

v = 8sqrt(h)

at 10 ft, v = 8sqrt(10)

at 20 ft, v = 8sqrt(20) = 16sqrt(5)

Answer 6

lol. thanks.

Answer 7

:) youre welcome; not sure if I anwered the second part ....but thats the best I got ;)
