Answer:
7.40m/s
Explanation:
The masses of the cars with their respective initial velocities are;
Since the two car stuck after collision, they all move with a common velocity in the same direction.
Let the velocity at which the two cars will be moving after collision be V.
From the conservation of momentum, in a closed system, momentum before collision is equal to momentum after collision.
Mathematically,
By substitution, we obtain;
Dividing through by 408, we obtain
Therefore,v=7.40m/s
Explanation:
The final velocity of the bale have vertical and horizontal components. So, we have:
According to conservation of energy:
Since the plane is flying due east, we have . Replacing in (1):
Now, we calculate the momentum of the bale:
From pythagoras theorem we know that:
