And we have our final answer!
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s
5500 pounds since 1 ton = 2K pounds, 3/4 of 2K is 1500, so 5500.
The surface area of a cube is:
A=6s^2 (It is just the area of 6 sides (squares) all having an area of s^2)
A=7.2^3=373.248 ft^3
