Consider a man with a thick padded punching glove who strikes a bag. He then strikes that same bag without a punching glove. Both punches travel at the same velocity. Which one exerts more force? Which one takes longer to stop?
Here's my understanding:
We know by newton's 2nd law that $F=ma$. With the glove there is more mass and therefore more inertia. So the glove should take longer to stop.
For force, with the glove there is more mass and once again there should be more force.
The answers state that the force with the glove is smaller and the glove takes longer to stop. I seem to have gotten the force one wrong so what did I do incorrectly?
Edit: I understand the correct solution. However I struggle to understand what's wrong with my solution. Why must I neglect the mass?
