In an isolated system two equal masses of the same geometry approach one another along the same line of action with equal but opposite velocity. The collision between them is perfectly INELASTIC. The linear momentum of the system BEFORE the collision equals - ANSWERzero True/ False Let us consider the floor to be zero level of gravitational potential energy. When the ball is fired, it has a non-zero potential energy with respect to the floor. -- Because the ball is above the floor, it DOES ...
