Question 7 • Physics I

Students perform an experiment in which they drop two eggs with equal mass from a balcony. In the first trial, the egg hits the ground and breaks. In the second trial, the egg hits a foam cushion and does not break or bounce. What conclusions about impulse can the students make?

Answer
A
The impulse cannot be determined without the mass and velocity of the eggs.
B
The impulse was greater in the first experiment because the egg broke.
C
The impulse was greater in the second experiment because the egg did not break.
D
The impulse was the same in both experiments because the egg came to a stop.
