1. The problem statement, all variables and given/known data 1.) does a ball thrown upward lose momentum as it rises? explain. 2.)a duck walks along a long thin raft in the water. what does the raft try to do? what hinders this action? 3.)a golfball and a football have the same kinetic energy, which ball has the greatest momentum? 2. Relevant equations 3. The attempt at a solution 1.) the decreasing velocity would temporarily change the momentum but ultimately the final momentum should equal the initial momentum. .)The raft trys to to shoot out and tip as the duck walks not sure what else. 3.) the more massive football has the greater momentum.
