Sphere X, of mass 2 kg, is moving to the right at 10 m/s.Sphere Y, of mass 4 kg, is moving to the left at 10 m/s.The two spheres collide head-on.The magnitude of the impulse of X on Y is:
A)twice the magnitude of the impulse of Y on X
B)half the magnitude of the impulse of Y on X
C)one-fourth the magnitude of the impulse of Y on X
D)four times the magnitude of the impulse of Y on X
E)the same as the magnitude of the impulse of Y on X

According to Newton's third law, for every action, there is an equal and opposite reaction. This means the magnitude of the impulse of X on Y is the same as the magnitude of the impulse of Y on X, regardless of their masses or velocities.

Sphere X, of Mass 2 Kg, Is Moving to the Right
