If your speed triples, you need times the distance to stop

9 Times

Explanation:

The stopping distance of a car (or any traveling object) is proportional to the square of the speed of the car.

This is a consequence of the work-kinetic energy theorem, which states that the work done on the car is equal to its loss of kinetic energy:

Since the final speed of the car is zero, its final kinetic energy, so we can write:

where

F is the force that stops the car (the force of friction)

d is the stopping distance

m is the mass of the car

v is the initial speed of the car

As we see from the equation, the stopping distance (d) depends on the square of the speed (). Therefore, it the speed is tripled, the stopping distance will acquire a factor , so we will need 9 times the distance to stop.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
