Compute the minimum distance that a truck slides on a horizontal
asphalt road if it is traveling at 20 m/s. The coefficient of sliding
friction between asphalt and rubber tire is 0.50. The mass of the
truck is 8000 kg.
The truck acceleration
"a=\\frac{F}{m}=\\frac{\\mu mg}{g}=\\mu g\\\\\n=0.50*9.8=4.9\\:\\rm m\/s^2"The distance
"d=\\frac{v_0^2}{2a}=\\frac{20^2}{2*4.9}=41\\:\\rm m"
