Short Answer

Expert verified

The height whent=6seconds is,424feet.

Step by step solution

01

Step 1. Given information

The height of the package is, ht=-16t2+1000.

We need to find the height whent=6seconds.

02

Step 2. Substitute t=6 in the given equation.

ht=-16t2+1000h6=-1662+1000=-1636+1000=-576+1000=424

The height whent=6seconds is,424feet.
