Two eggs of equal mass fall from the same heigzzd+8h0q iy8uq )u j j4gi g+-b0ti6xwht onto a padded floor. One of wvd/6 *wmi uoh1t;k *s y1ezv/them is broken while the other one bounces upm*vk 611;wd v*/zyeo/sw i uthwards intact. The time of collision is the same for both. Which of the following correctly describes the egg that exerts more force on the floor and the reason?
A. Egg exerting more force is the broken one; Reason is Greater change in momentum
B. Egg exerting more force is the one that bounces; Reason is Less change in momentum
C. Egg exerting more force is the broken one; Reason is Less change in momentum
D. Egg exerting more force is the one that bounces; Reason is Greater change in momentum
