a rock is dropped from a height of 32 m. how many seconds it takes for the flare to hit the ground? use the formula below where h0 is the initial height. approximately how long will is take the object to hit the ground?
h(t)=−16t2+h0
question 3 options:
0.8 sec
1.4 sec
2.3 sec
5.1 sec

t = 1.4 sec.

This is an example of freefall, here the height is given as function of time and we want to know how long take to the rock from a height of 32m reach the ground.

With h₀ = 32 m, and set h(t) = 0 due the height when the rock hit the ground is 0.

h(t) = -16t² + 32 = 0

Solving:

-16t² + 32 = 0

32 = 16t²

Clear the equation for t:

t = ±√32/16

t = ±1.414s

Take the positivie value since time can't be negative:

t = 1.414s ≅ 1.4s

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
