Question

A ball is thrown upward from the top of an 80ft building so that its height in feet above the ground after t seconds is h(t)=80+64t-16tˆ2.


question: what is the acceleration at time t....

Answer 1

Take the double derivative.

Answer 2

You end up with -32.

Answer 3

yes, then?

Answer 4

That's it.

Answer 5

ay, my teacher didnt teach us today, but we have excercise today...

Answer 6

velocity is the derivative of position

V = -32t + 64

acceleration is the derivative of velocity

A = -32

Answer 7

m/s^2

Answer 8

－32 means A= -32? means acceleration???

Answer 9

-32 ft/(s^2) yes.

Answer 10

In other words, gravity.
