Answer:
The value is
Explanation:
From the question we are told that
The relationship between the number of whooping cranes and the number of decades is
The exponential relationship is
Now from the given equation we have that
So comparing this equation obtained an the given exponential relationship we have that
Let say the two train cars are of masses and
now if the speed of two cars are and
then we can say that the momentum of two cars before they collide is given by
here two cars are moving in opposite direction so we can say that the net momentum is subtraction of two cars momentum.
Now since in these two car motion there is no external force on them while they collide
So the momentum of two cars are always conserved.
hence we can say that the final momentum of two cars will be same after collision as it is before collision
