Two studer's are essisting their teacher with a korosimpulse demonstretion Ong student sils on a large skate can't while the other student puthes him. Ignoring any effects of friction or air resistance, which of Whatlookooking/is/live about the total momentum of this system? a An object which is moving hes zero momentum This problem cannot be solved. B The force mullipled by the time equals the mass multiplied by the change in velocity. It is greater before the collision than after the collision Momentum dianga equalis impulse multiplied by lime, then divided by the fonce.

## Step 1<br />The problem involves the concept of momentum in physics. Momentum is a vector quantity, which means it has both magnitude and direction. It is defined as the product of an object's mass and its velocity.<br /><br />## Step 2<br />The law of conservation of momentum states that the total momentum of a system remains constant if no external forces are acting on it. This means that the total momentum before an event (like a collision) is equal to the total momentum after the event, assuming no external forces are involved.<br /><br />## Step 3<br />In this problem, we have two students on a large skate. One student is pushing the other, which means there is an interaction between the two students. However, the problem specifies that we should ignore any effects of friction or air resistance, which means we are assuming no external forces are acting on the system.<br /><br />## Step 4<br />Given this assumption, the total momentum of the system (the two students on the skate) should remain constant. This means that the total momentum before the push is equal to the total momentum after the push.
