Answer:
The height of the package when it was released was 1102.5 meters
Explanation:
A package is dropped from a hovering helicopter
Dropped means the initial velocity of the package is zero
The package takes 15 seconds to strike the ground
Ignore the air resistance
We need to know the height of the package when it was released
, where h is the height of the package
from the ground, u is the initial velocity, g is the acceleration of gravity
and t is the time
u = 0 , t = 15 seconds , g = 9.8 m/s²
h = 1102.5 meters
<em>The height of the package when it was released was 1102.5 meters</em>
Answer:
What she can do to collect the data is;
B. Gather a few oranges and see how many seeds are in each
Explanation:
The quantity Katie wants to find out is the number of seeds contained in each orange
Therefore, the required population = The number of seeds in a given orange
The method of estimation of the number of seeds per orange is sampling method, whereby the number of seeds in each of the orange in the sample is used to as an hypothesis as to the number of seeds expected in each orange of the entire population.
Therefore, in order to collect the data, she can gather a few oranges and see how many seeds are in each.
