3.60 kg·m/s
The total momentum after the collision can be found by adding up the momenta of the two objects. Since the two objects have the same mass and velocity, their momenta are equal.
The momentum of each object is given by the formula p = mv, where p is the momentum, m is the mass, and v is the velocity.
For each object, the momentum is:
p = (1.00 kg)(1.80 m/s) = 1.80 kg·m/s
Since the two objects have the same momentum, the total momentum after the collision is:
Total momentum = 1.80 kg·m/s + 1.80 kg·m/s = 3.60 kg·m/s
Therefore, the correct answer is 3.60 kg·m/s.
