3. A ferry boat is 4.0 m wide and 6.0 m long. When a truck pulls onto it, the boat sinks 4.00 cm in the water. What is the weight of the truck?

Respuesta :

Answer:

Explanation:

The weight of the truck will equal the weight of the displaced water.

Assuming fresh water and that the sides of the ferry are vertical,

The volume of the water displaced is

6.00(4.00)(0.0400) = 0.960 m³

that volume of water weighs

0.960 m³(1000 kg/m³)(9.81 N/kg) = 9,417.6 = 9.42 kN
