An airplane is delivering food to a small island. it flies 100 m above the ground at a speed of 150 m/s .

where should the parcel be released so it lands on the island? neglect air resistance.
express your answer to two significant figures and include the appropriate units.

We have that for the Question "An airplane is delivering food to a small island. It flies 100 m above the ground at a speed of 150 m/s ." it can be said that the distance of release is given as

d=623.7m

From the question we are told

An airplane is delivering food to a small island. It flies 100 m above the ground at a speed of 150 m/s .  

Where should the parcel be released so it lands on the island? Neglect air resistance.

Generally the equation for the   is mathematically given as

Therefore

The distance of release is given as

d=150*4.158

d=623.7m

The airplane should release the parcel m before reaching the island

Explanation:

The height of the plane is , and its speed is v=150 m/s

When an object moves horizontally in free air (no friction), the equation for the y measured with respect to ground is

   [1]

And the distance X is

x = V.t     [2]

Being t the time elapsed since the release of the parcel

If we isolate t from the equation [1] and replace it in equation [2] we get

Using the given values:

x = m

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
