4. What is the smallest number of whole logs
(density = 705 kg/m³, radius = 0.087 m, length = 2.73 m) that can
be used to build a raft that will carry 5 people, each of whom has
a mass of 74.5 kg?
logs
5. A block of mass 0.55 kg and density 3000
kg/m³ is completely submerged under the water in static equilibrium
on top of a spring (k = 50.0 N/m) that is fixed to the bottom of
the container as shown in the figure. How much is the spring
compressed? (the density of water is 1000 kg/m³).
