# Force Problem with Punching Glove?

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?

• Neglect the mass of the glove - this problem is mainly about impulse. Mar 22 at 4:40
• Given your assumption, you were on the right track. This problem doesn't spell everything out very well. I suspect you are supposed to think of the glove as padding more than extra mass. Mar 22 at 4:59
• @dandan0101 Thanks I understand the solution. However I struggle to understand what's wrong with my solution. Why must I neglect the mass? Mar 22 at 5:05
