The distance d that an object falls is directly proportional of the square of the time of the fall, t. A person who is parachuting for the first time is told to wait 19 seconds before opening the parachute. If the person falls 64 feet in 2 seconds, find how far he falls in 19 seconds.

Question

anonymous · Answer

64/2 = 32
32x 19 = 608

anonymous · Answer

I believe this is your final answer if all constants are fixed and no gravity or other factors are applied.

ok thanks man

anonymous · Answer

d = kt^2
64 = k*2^2
k = 16
so
d = 16t^2
when t = 19
d = 16*19^2
d = 5776

oops he is right ^ I guess I didn't read the question fully.

anonymous · Answer

yea - its t^2 - thats what you missed
