we know that anything times zero = 0; so either 16t = 0 or 5-t =0

when t=0 that makes no sense, so it can be disregarded as a false positive; lets go with t=5 and see where that gets us

so we mulity 5 x 5= 25 then 25 x 16

h = 80(5) - 16(5)2 0 = 400 - 16(25) 0 = 400 - 400 .... looking like a possibility

sorry i am lost if it is correct would the answer b 0 or 400

if the ball is dropped from a certain height, then t=0 makes no sense; but if we are starting the ball at ground level, and throwing it up, then maybe t=0 is an option

ok i get that

Since it does not state that we "drop" the ball, itd be safe to include 0 id assume.

at any rate; 5 seconds is what it takes after being "released" to hit the ground
