2 Kayaks have been used for thousands of years to hunt and fish in Arctic regions.
The total volume of a particular kayak is
285 litres (which is 0.285 m). It has a mass of
75 kg. The man using it has a volume of
0.066 mº. When sitting in the kayak, half of
man's volume is inside the kayak. The density
of the human body is about 1000 kg/m.
a Calculate the density of the empty kayak.
b Calculate the mass of the kayaker.
c What is the overall density of the kayak and the kayaker when it is being paddled?
