2. A girl on a bike is accelerating at a rate of 5 m/s2 and has a total mass of 60 kg. How much force is the girl applying to her bike to move at this rate? *

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
