To solve this problem, we can use the principle of conservation of momentum.
Let's assume that the final velocity of the 2 kg object is v1, and the final velocity of the 4 kg object is v2.
According to the conservation of momentum, the total initial momentum before the collision is equal to the total final momentum after the collision.
The initial momentum of the 2 kg object is zero because it is initially at rest, and the initial momentum of the 4 kg object is also zero because it is initially at rest. Therefore, the total initial momentum is zero.
The final momentum of the 2 kg object is 2 kg x v1, and the final momentum of the 4 kg object is 4 kg x v2. Therefore, the total final momentum is (2 kg x v1) + (4 kg x v2).
Since the total initial momentum is equal to the total final momentum, we can write the equation:
0 = (2 kg x v1) + (4 kg x v2)
Simplifying the equation:
0 = 2v1 + 4v2
Now, we need additional information to solve for the final velocities. This could be given in terms of the coefficient of restitution or the masses and initial velocities of the objects. Please provide more information, so we can continue the calculation.
