Astunt car with a mass of 1,000 kilograms crashes into a tree on a movie set. during the collision, the acceleration of the car was 3 meters/second2. what was the force of impact of the collision on the car?

The answer is Force is equal to 3000N

Step By Step Explanation:

1- Taking into account Newton's second law, we know that the acceleration that a body acquires is directly proportional to that resulting from the forces acting on it, and has the same direction as that resulting.

2-This law is expressed with the formula F = ma where (F) represents force, (m) represents mass and (a) represents acceleration.

3- having this we can continue to replace the given values, in said formula:

F = (1000kg)(3m/s^2)

F = 3000N

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 =

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
