An egg gets dropped from a height of 0.1 meters and cracks. A second egg gets dropped from the same height but this time it lands on a glass of water and does not break. In terms of impulse.
1st egg experienced more impulse
2nd egg experienced more impulse
both experienced the same impulse
An egg gets dropped from a height of 0.1 meters and cracks. A second egg gets dropped from the same height but this time it lands on a glass of water and does not break. In terms of force and time, the second egg must have experienced...
more force, but less time
less force, but more time
more force, and more time
less force, and less time
