You have been hired to design a spring-launched roller coaster that will carry two passengers per car. the car goes up a 11-m-high hill, then descends 17 m to the track's lowest point. you've determined that the spring can be compressed a maximum of 2.0 m and that a loaded car will have a maximum mass of 430 kg . for safety reasons, the spring constant should be 15 % larger than the minimum needed for the car to just make it over the top.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

360seconds i 1 hr

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 =
