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...

21.

A stunt person jumps from the roof of a tall building, but no injury occurs because the person lands on a large, air-filled bag. Which one of the following best describes why no injury occurs?

The bag reduces the impulse to the person

The bag increases the amount of time during which the momentum is changing and reduces the average force on the person

the bag decreases the amount of time during which the momentum is changing and reduces the average force on the person

The bag increases the amount of time the force acts on the person and reduces the change in momentum
