When we went to Goldstream we saw the oil boom in the river. People put it in the river to capture the oil and the dead fish. Because oil is less dense than water, it floats on the surface of the stream. The oil boom is for filtering contaminants. The fish are dying because the oil floats on the surface of the water, so the oxygen cannot dissolve into the water.

How much force did the truck hit rock wall with if driver was not speeding?

p= mv

m= 63500 kg (http://www.tetracom.ca/transtalk/?p=2151)
v= 70km/h= 19.4 m/s

p=(19.4)(63500)
p=1231900 N/s

F= p/t

p= 1231900 N/s
t= 3 seconds (estimated)

F= (1231900)/(3)
F= 410633.3 N
