Comparing Impulse in Collisions: Which Ball Experiences a Greater Magnitude?

Click For Summary
In the discussion about the impulse experienced by two equal mass balls dropped from the same height, participants analyze the scenario where the red ball rebounds higher than the blue ball. The key point is that impulse is defined as the change in momentum, and since both balls have equal mass and are dropped from the same height, they experience the same magnitude of impulse during their collisions with the floor. Some participants express uncertainty about the answer, with one suggesting that the impulse cannot be determined without knowing the time intervals and forces involved. Ultimately, the consensus leans towards the idea that both balls experience the same magnitude of impulse, highlighting the conservation of momentum in this context. The discussion emphasizes the relationship between impulse and momentum in collision scenarios.

Homework Statement


2 equal mass balls (one red one blue) are dropped from the same height and rebound off the floor. the red ball rebounds to a higher position. which ball is subjected to the greater magnitude of impulse during its collision with the floor?

a. it's impossible to tell since time intervals and forces are unknown.
b. both balls were subjected to the same3 magnitude impulse.
c. blue
d. red


Homework Equations



impulse = f*deltat

The Attempt at a Solution



i think the answer is b, but I'm not sure

kallisti, welcome to PF! What's the equation that relates impulse to momentum?
 
impulse equals change in momentum.

so are they the same, since momentum is conserved?

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
