What is the acceleration?

v(t) = 128 -32t?

and after 3 seconds?

Question

What is the acceleration?

v(t) = 128 -32t?

and after 3 seconds?

anonymous · Answer

you can take the derivative of this function, since acceleration is the second derivative of the position function or the drivative of the veloctiy function

anonymous · Answer

@woobin do you have to do it using the definition?  because otherwise you do it in your head

anonymous · Answer

What's the 3 seconds about, distance?

anonymous · Answer

gm satellite

anonymous · Answer

i don't know how to do it because if i take the derivative the acceleration will become a = 32 am i correct?

amistre64 · Answer

-32

anonymous · Answer

$$v(t)=128-32t$$
$$a(t)=v'(t)=-32$$

anonymous · Answer

a(3)=-32

anonymous · Answer

on account of "gravity sucks"

amistre64 · Answer

im sure there is a sec^2 under it all?

anonymous · Answer

@estudier nope it is about the acceleration after 3 seconds.

anonymous · Answer

Need some initial conditions..

amistre64 · Answer

the acceleration is constant; its slowing down

anonymous · Answer

@sattelite73 how bout if u plug in the 3 seconds in the acceleration what will be the asnwer?

anonymous · Answer

Plug 3 into -32?

anonymous · Answer

a(3)=-32

amistre64 · Answer

round peg square hole filosophee eh lol

anonymous · Answer

into the a(t) = -32

anonymous · Answer

Why would u want to plug 3 into -32?

amistre64 · Answer

integrate it from 0 to 3?

anonymous · Answer

because that's the condition.

anonymous · Answer

the derivative of acceleration is jerk

anonymous · Answer

i'm finding the acceleration after 3 seconds..

anonymous · Answer

Oh u mean evaluate the constant function a(t) at t = 3?

anonymous · Answer

yup

anonymous · Answer

constant.

anonymous · Answer

constant what do u mean? what will be the answer?

anonymous · Answer

What do u think the -32 means?

amistre64 · Answer

it helps if you have some idea as to what your own question is asking for ...

anonymous · Answer

how about i'll type the whole problem can u answer it?

amistre64 · Answer

oh, so your keeping secrets are ya :)  that would be a good move

anonymous · Answer

you mean thats the whole problem?

anonymous · Answer

He moved onto projectiles now.

anonymous · Answer

That's the whole question..
