Ball x of mass 1.0 kg and ball y of mass .5kg travel toward each other on a horizontal surface. both balls travel with a constant speed of 5m/s until they collide. during the collision, ball y exerts an average force with a magnitude of 40 n for 1/6 s on ball x. which of the following best predicts ball y's momentum after the collision?

a. ball y will travel at a speed less than 5m/s in the same direction of travel as before the collision.
b. ball y will travel at a speed less than 5m/s in the opposite direction of travel as before the collision.
c. ball y wil travel at a speed greater than 5m/s in the same direction of travel as before the collision.
d ball y's motion cannot be predicted because the impluse on it is not known.
