A firecracker shoots up from a hill 150 feet high with an initial speed of 95 feet per second. Using the formula H(t) = −16t2 + vt + s, determine how long it will take the firecracker to hit the ground.
1. Let's draw a diagram. 2. LEt's make a variables list 3 Find der formulas tu need!
4. Solve it! remember which formulas need to be 'combined'!
Do you just want the answer?
blue bird! go back to your other question! THIS MA TOWN!
oooh wait. this aint physics...
How would i make a variables list?
you just need to find the end points!
I'm confused :o
I thought you only plug in the numbers to the equation but i'm unsure if that's correct or how to do it even if it is correct
v=95 ft/s H(t)=150
solve for s!
wait...what's s? solve for t, silly me
ok but there is also a s!?
I tried to solve but i'm soooo confused
let H(t) = 0 then solve for t
really? shoot. I suck at even trinomials now huh
maybe s is given elsewhere in your textbook
no it isn't :o
@Romero yes please can i have the answer
@lgbasallote wat is s?
i'd like to say it's the distance traveled
Is the answer 7.2 seconds?
dunno. doesnt your txtbook ahve the answer?
no @lgbasallote is the answe 7.2s ?!
i'm doing an online course not from a textbook!
lol shouldnt @NotTim be answering this o.O wait..ill check
i dont wanna do math...
it;s what my calculator said
ok thank you all :)
