24 1 point An example of an elastic collision would be a catcher catching a baseball a toy gun shooting a dart two pool balls hitting each other a football player tackling another Previous
27 1 point A Ball A and a Ball B collide elastically. The initial momentum of Ball A is 2,00kgm/s and the initial momentum of Ball B is-5.00kgm/s. Ball A has a mass of 4,00kg and is traveling at 2.50 m/s after the collision. What is the velocity of ball B if it has a mass of 6.50kg? 0.462 m/s 2.17 m/s -2.62 m/s 0.382 m/s Previous Next
