WebMomentum is a vector quantity, so the total momentum is found by a vector sum. Since the momentums of the two objects are in opposite directions one of them is going to be negative. Since positive answers are preferred over negative ones, let's choose right as the positive direction. This gives us a total momentum of +12 kg m/s.

WebEnergy conservation can be seen in any process involving the transformation of energy from one form to another. It is closely related to the law of conservation of energy. In physics, the law of conservation of energy states that energy cannot be created or destroyed, but can change from one form to another. This is a fundamental law of all of ... WebProblems 1.
