Let's calculate the momentum of Fiona, given by the product between its mass and its speed:
Now let's compare it with the momentum of the other animals:
a) the mass of the sea turtle is missing, so we cannot calculate its momentum.
b) the momentum of the dolphin is
c) the momentum of the horse is
d) the momentum of the lion is
And we can see that the correct answer is b), because the momentum of the dolphin is greater than the momentum of Fiona.

Answer:
The drop time ball 1 is less than the drop time of ball 2. A further explanation is provided below.
Explanation:
The net force acting on the ball will be:
⇒
Here,
F = Force
m = mass
g = acceleration
Now,
According to the Newton's 2nd law of motion, we get
⇒
To find the value of "a", we have to substitute "" in the above equation,
⇒
⇒
We can see that, the acceleration is greater for the greater mass of less for the lesser mass. Thus the above is the appropriate solution.
