Answer:
a = 3,0 m/s²
Explanation:
En este ejercicio se pide calcular la aceleracion del cuerpo, usemos las ecuaciones de cinematica en una dimensión.
v= v₀ + a t
como el corredor parte del reposo si velocidad inicial es cero
v = at
a = v/t
calculemos
a = 12 /4,0
a = 3,0 m/s²
Answer:
I can't see it because it's too blury. try to search it
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:
I think its 12 cm itself. Because in the question it is said that the length is same in all temperature
