Question

I missed the stream clean on November 8.† But if I had and if it had been more of a river clean, I might have been in a boat and I might have found a discarded refrigerator. Let’s say that the boat was rectangular in shape with dimensions of 4.88 m long and 1.22 m wide. When the refrigerator is loaded onto the boat, the boat rides 1.50 cm deeper in the water. What is the mass of the refrigerator?

Answer 1

Extra volume of water displaced V = 4.88m x 1-22m x (1.50x10^2m) = 8.9034 X10-2m3 Buoyant force = weight of refrigerator. veg = mg > M = VPw [w = 1000 kg / m3] M=8-9034x10-2m² x 1000 kg lm3 [M=89.034 kg)
