An interacting system of two objects has no external force acting on the system. The first object has a mass 2.00 kg and is moving with a velocity (2.00 m/s) + (1.00 m/s) at time t = 0.00 s. The second object has a mass 3.00 kg and is moving with a velocity (-1.00 m/s) + (1.00 m/s) at time t = 0.00 s. The second object is moving with a velocity (2.00 m/s) + (-1.00 m/s) at time t = 1.00 s.
(a) What is the total momentum of the system at time t = 0.00 s?
(b) What is the velocity of the first object at t = 1.00 s?
