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.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
