1. You throw a ball purely horizontally through the air, it bounces off a wall and continues at about the same speed back towards you also purely horizontally (pretending gravity isn't a factor). Then can we say that the impulse delivered onto the ball from the collision with the wall is about double the momentum it had at the start? True False 2. The total momentum of a system subject to only internal forces (one that is isolated) is conserved....
