# the number of feet any object will fall?

The number of feet any object will fall in a number of seconds is found by the formula:

s = ½ gt²

If an object is dropped from an airplane, how far will it fall in 10 secs?

use the formula:

S=the number of feet an object will fall

t=the number of seconds

g=32 ft per second per second

TY

Update:

really, you should be able to do this. it's just plug & chug !

s = (1/2)*32*10^2 = (1/2)*32*100 = 16*100 = .........

sorry I'm really confused because

g=32 ft per second per second

so I thought 32 * 10secs = 320!! or is that a typo?

Update 2:

32*10 is 320, but that's not what the equation says.

Starting with the exponents you do 10^2, which = 100.

Next you do 1/2 of 32, which is 16.

You're left with 16*100 = 1600.

Still confused!

OK so the formula states:

g=32 ft per second per second and there's 10 seconds!

so I plug in 32*10seconds

so I ended up with s=1/2*32*10secs*10^2 (BrDMAS)

s= 160*100=16000 LOL

this is really bothering me because if there is only 1 second then yes 32 ft makes sense but 10seconds.

but it says 32ft per second per second....so I assume that it means

32 times per second multiplied by 10seconds!

just imagine an object is falling from the sky and

it fell 32 ft per second

and so it is asking how far will it fall in 10 seconds

so yes if an object fall 32ft per second times 10 seconds that'll be 320ft

anyway gaaaah why is it so confusing maybe I'm missing something here and my logic is bad.

Update 3:

EDIT:

The formula says: s=1/2*32*10^2

NOT s=1/2*32*10secs*10^2

I don't know what to say other than that you need to do a review of basic algebra

OK, I see it now, I suppose I need to review basic algebra. Because if I just have to rely on my own theory here I suppose it is confusing.

s = ½ gt²

so yes

s=1/2 32 * 10 ^2

If an object is dropped from an airplane, how far will it fall in 10 secs?

but still I believe it is confusing though

it'll much much easier if the formula given was

s=1/2 g ^2

because then

g=32 ft per seconds makes sense!

because the question asks how far will it fall in 10secs!

so yes 32ft * 10 secs to the power of 2 =1600 then haha

or that

g=32 ft

compares to

g= 32 ft per second per second

Relevance

really, you should be able to do this. it's just plug & chug !

s = 0.5*32*10^2 = 0.5*32*100 = 16*100 = .........

=======

ft

------ is the unit for "g"

sec²

it is multiplied by t² , ie sec²

ft

------ x sec² => feet as the unit

sec²

also, in multiplication, order doesn't matter, so do it anyway you like

0.5 x 32 x 10 x 10 = 1600 ft

• just replace g & t by their values:

S=1/2 * 32 * 10^2

= 1/2 * 32 * 100

= 1600 ft
