3. Will a ( 120-mathrm{kg} ) raft of density ( 700 mathrm{~kg} / mathrm{m}^{3} ) hold a ( 60-mathrm{kg} ) person above water? Show all your work.

Question

Accepted Answer

Step:1 ：(V = frac{m}{rho} = frac{120}{700} = 0.1714 mathrm{m}^{3})Step:2 ：(A_{raft} = frac{V}{h} = frac{0.1714}{0.1} = 1.714 mathrm{m}^{2})Step:3 ：(m_{total} = 120 + 60 = 180 mathrm{kg})Step:4 ：(F_{buoyancy} = rho_{water}times V_{rafted}times g = 1000 times 0.1714times 9.81 = 1113.49 mathrm{~kg})
