Buoyant force is equal to the weight of the total amount of liquid displaced by an object when submerged partially or completely in the fluid. This means that if an object that has a volume of 2m³ has 50% (1m³) of its volume submerged in water, the buoyant force will be equal to the weight of 1 m³ of water, this is about 1000kg.
With this in mind, the buoyant force will be equal to the weight of the amount of fluid that has the same total volume as the object when the object is completely submerged, this is to say, it has its total volume under the fluid.

Answer:
1.5 m
Explanation:
Using the law of conservation of energy
Gain in potential energy by the skateboarder= Loss in kinetic energy by the skateboarder
PE=KE where KE represent potential energy, PE represent potential energy
where m is mass of skateboarder and v is velocity of skateboarder
PE=mgh where m is the mass of skateboarder, g is acceleration due to gravity which in this case is taken as and h is the highest point reached by the skateboarder. Equating PE=KE we have
and since m are on both LHS and LHS, the cancel
} and making h the subject of the above formula
Substituting v with 5.4 m/s and g as we obtain
Rounded off, h=1.5 m

The critical thing to note here is the question "Will silver sink or float when places in water?" The reason for this question is that if it sinks, the volume increase will be exactly the volume of the silver. If it floats, then the volume increase will be that of the volume of water the silver displaces. So looking at the density of silver at 10.5 g/cm3, it's a lot denser than that of water which is close to 1 g/cm3. So the silver will sink. Now the question is "What's the volume of 5.35 g of silver?" That number is simply the mass of the silver divided by the density of the silver, giving
volume = 5.25 / 10.5 = 0.5 cm3.
So the volume of silver is 0.5 cubic centimeters. Since a ml is a cubic centimeter, you just need to add up the volume the water with the volume of the silver to get the final answer, giving:
11.2 + 0.5 = 11.7 ml
Note: The exact density of water isn't needed since the volume calculations would be the same regardless. However, if the silver had been less dense than the water, then the exact density of the water would have been needed to calculate how much water would have been displaced.</span>
