However, they have been losing money over the past couple of years because of what it costs to maintain their cows they use for breeding. To help offset their losses, Donna focused on making sure the calf weight at weaning was larger than in past. She also included nutrients

direction then it would have a increase of KE. In which case if it is just there to resist then the ke is decreased depending if the ball doesn’t already have wings. 54. if two object have the same KE then the momentum is the same. Not applying the mass of the item nor having to include the environment. It both was to move with no other KE to resist then both would be going at same momentum whether is big or small.

American University in Cairo Department of Physics Final Exam Physics (111) Time: 2 Hours Answer the following problems 1)The mass of the blue puck in Figure is equal to 1.2 the mass of the green one. Before colliding, the pucks approach each other with momenta of equal magnitude and opposite directions, and the green puck has an initial speed of 10.0 m/s. Find the speeds of the pucks after the collision if half the kinetic energy is lost during the collision. speed of Blue
