Question

The distance, d, that an object falls is directly proportional to the square of the time, t, it has been in free fall. An object that has been in free fall for 8 seconds has fallen 1024 feet. Determine the distance the object has fallen if it has been falling for 3 seconds.

d= ___ ft

Answer 1

I think its 384 can someone confirm

Answer 2

too bad you didn't show your work ...
d = kt^2, so
64k = 1024
k = 16
16*9 = 144

and in fact, g = 32 ft/s^2, so d = 1/2 g t^2 = 16t^2
