A projectile is fired with an initial speed of 100 m/s at an angle of 47 above the horizontal. a. Determine the total time in the air.
b. Determine the maximum height reached by the projectile.
c. Determine the maximum horizontal distance covered by the projectile.
d. Determine the velocity of the projectile 5 s after firing.

explanation:

could i give you a exaplo that could you?

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 =
