- In a collision between two objects of unequal mass, which object receives a greater magnitude impulse? Select one: a. the object of smaller mass b. the object of larger mass c. They receive equal magnitude impulses.Two equal mass balls (one white and the other black) are dropped from the same height, and rebound off the floor. The white ball rebounds to a higher position. Which ball is subjected to the greater magnitude of impulse during its collision with the floor? Explain.Problem 2.
