2. A 36.5kg dog runs across a field at 11.2m/s[North] on a very dark night. The poor dog could not see the chain link fence in front of it, and it crashed into the fence, bouncing back onto the grass at 4.00m/s[South]. The dog was in contact with the fence for 0.674s. a. What was the momentum of the dog as she ran across the field? b. What impulse was applied to the dog? c. What average force did the fence apply to the dog?
