A soccer ball (mass = 0.43 kg) is moving at a speed of 20 m/s when it is kicked with a force of 300 N resulting in it going in the opposite direction with the same speed as before. What is the magnitude of the impulse delivered to the ball?
a. 0, because the before and after momenta cancel each other.
b. 8.6 kg·m/s
c. 17 kg·m/s
d. 2 600 kg·m/s
