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?
a. the impulse was greater in the first experiment because the egg broke.
b. the impulse was greater in the second experiment because the egg did not break.
c. the impulse was the same in both experiments because the egg came to a stop.
d. the impulse cannot be determined without the mass and velocity of the eggs.

See below

Explanation:

In the experiment, the eggs where throw from the same balcony. While they fall, they are affected by the Gravity acceleration and they keep gaining speed by the time. With this in mind we can deduce that they had the same speed when they reached the ground.

Also, it is know the eggs have the same mass, because of they have the same speed and mass at the moment of the fall the impulse should be the same, according to this equation.

Impulse (I) = Force (F) * Time (T)                                          *(1)

Knowing that Force is the product of Mass and Acceleration we can re-writte this equation.

I = Mass (M) * Acceleration (A) * Time

And Acceleration is the ratio between Velocity and Time.

I = M * (Velocity/Time) * Time

I= Mass * Velocity

Because the eggs have the same mass and had the same velocity at the final moment the Impulse is the same.

This means that conclusions A and B are false. The eggs had the same impulse.

C is true, the impulse was the same in both experiments, because the eggs where throw from the same height soo their falling time was the same.

D is false, because we can know that Impulse it the product of Force and Time, a constant force will generate the same Impulse at a set time, according to equation (1).

The answer is C on edgen

Explanation:

C. The impulse was the same in both experiments because the egg came to a stop.
