Jamal is playing in the arcade at Six Flags. At one booth, he throws a 0.5 kg ball with a velocity of 21 m/s andhits a 0.2 kg bottle sitting on a shelf. The bottle goes flying forward at 30 m/s. a). What is the velocity of the ball after it hits the bottle? b). If the bottle was more massive but flew forward with the same final velocity, how would this affect the final velocity of the ball?

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

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 =
