Assume you are driving 20 mph on a straight road. also, assume that at a speed of 20 miles per hour, it takes 100 feet to stop. if you were to increase your speed to 60 miles per hour, your stopping distance is now:

900  feet

Explanation:

Given

Velocity

it take 100 feet to stop

Using Equation of motion

where

v,u=Final and initial velocity

a=acceleration

s=distance moved

When velocity is 60 mph

s=900.08 feet

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
