Question

If an object is falling with a position function P(t)=-16t^2+2000

how do i A) find the average volocity on the interval [4,5]?

B)show that at t=4.5, the velocity is the same as the average of the interval.

Answer 1

pivots matrix? sorry im very confused

Answer 2

\[\frac{f(5)-f(4)}{5-4}=avg.velocity\]

Answer 3

er... P(5) - P(4) might be more proper tho
