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

[kallisti]

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?

 

[omgitsmonica]

impulse equals change in momentum.

so are they the same, since momentum is conserved?
