Two UVM hockey players of equal mass and moving at equal speeds, are on a collision course. After the perfectly inelastic collision, they move away together at half their initial speed. Find the angle between the initial velocities of the two women. Enter your answer in degrees. (without entering units)

what is the question because that is not a question.

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 =
