We use the formula, to calculate the volume of water displaced by concrete canoe,

Here, W is the weight of concrete canoe and
is the specific weight of water and its value is
.
So,
.
Now the volume of water occupied in ultra lightweight kevlar canoe,

Here, w is weight of kevlar canoe.
So,

Thus, the volume of water displaced,
.
Hence, the volume of water displaced canoe compared to an ultra-lightweight kevlar canoe is 
Velocity, direction, or both at the same time.
You performed 0 work for the fact that work means the distance of movement made on an object not the amount of force it is exposed to. 0 work because it didn't move
