7. Ball X of mass 1.0 kg and ball Y of mass 0.5kg travel towardeach other on a horizontal surface. Both balls travel with aconstant speed of 5 m/s until they collide. During the collision,ball Y exerts an average force with a magnitude of 40N for 1/6s onball X . Which of the following best predicts ball momentum afterthe collision?
A Ball Y will travel at a speed less than 5 m/s in the samedirection of travel as before the collision.
B Ball Y will travel at a speed less than 5 m/s in the oppositedirection of travel as before the collision.
C Ball will travel at a speed greater than 5 m/s in the samedirection of travel as before the collision.
D Ball Y motion cannot be predicted because the impulse on it isnot known.
The answer is C but I do not understand why. Please refrain fromusing any Calculus
