Two objects in a closed system collide while moving directly toward each toward. Each has a mass of 1.00 kg and is moving at 1.80 m/s. What is the total momentum after the collision?
A. 1.80 kg x m/s
B. 3.60 kg x m/s
C. 0.90 kg x m/s
D. 0.00 kg x m/s
The total momentum after the collision can be calculated using the law of conservation of momentum. According to this law, the total momentum before the collision must be equal to the total momentum after the collision.
The momentum of an object is given by the equation: momentum = mass x velocity
Since both objects have the same mass and velocity, their momentum before the collision is given by: momentum = (mass1 x velocity) + (mass2 x velocity) = (1.00 kg x 1.80 m/s) + (1.00 kg x 1.80 m/s) = 1.80 kg x m/s + 1.80 kg x m/s = 3.60 kg x m/s
Therefore, the correct answer is B. 3.60 kg x m/s.
