Solve the system of equations given in the previous hint, and find an expression for x1x1x_1 in terms of the following variables: x0Ax0Ax_0A, the initial position of puck A; x0Bx0Bx_0B, the initial position of puck B; v0Av0Av_0A, the initial speed of puck A; and v0Bv0Bv_0B, the initial speed of puck B. Note that since we are now using the initial speeds of the pucks, the two equations become:

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 =
