practice

  1. A 20 km long, 8 m wide, two-lane highway is to be paved with a 4 cm thick layer of asphalt. A fleet of three dumptrucks is to be employed, each with an empty mass of 20 metric tons and a carrying capacity of 20 m3. Asphalt with a density of 0.72 g/cm3 will be used. Determine …
    1. the total volume of asphalt needed,
    2. the number of dumptruck loads required, and
    3. the gross mass of each truck.
  2. Determine which of the following expressions are dimensionally consistent.
         
    v2 = 2ax x = vt + ½ at3
    tan θ =  v
    x
         
  3. Write something else.
  4. Write something completely different.
