- 1 2 Your Sense Of Wonder Prompts You To Place A Firecracker In A Small Box Light It Then Close The Box The Box Expl 1 (45.34 KiB) Viewed 12 times
Your sense of wonder prompts you to place a firecracker in a
small box, light it, then close the box. The box explodes into
several pieces that fly off in different direction.
Your friend now notes: "At first there was zero momentum in this
system, but after the explosions several pieces were moving, so now
there was momentum. This shows that the principle of the
conservation of momentum does not hold during explosions."
Is your friend right? Explain your answer.
PLEASE ANSWER BOTH
A collision experiment is performed with two gliders on a level, frictionless track. The velocities of the gliders before and after the collision are shown in the diagram. Before collision After collision y = 0 Ai 04s Üst = 0 A Α. X X In this situation, is the magnitude of the change in momentum of A greater than, less than or equal to the magnitude of the change in momentum of X? Explain.
