Question

Edwin and cam are playing a golf. Edwin putts his golf ball at a velocity of 3 m/s and it hits Cams golf ball.Both golf balls have a mass of 0.15 kg. Edwin’s golf ball comes to a complete stop after it collides with Cams golf ball. According to the law of conservation of momentum. What should the resulting velocity of cams golf ball be if it was at rest before colliding with Edwin’s golf ball?

A:Equal tot he velocity of Edwin’s golf ball before they collided

B:twice the velocity of Edwin’s golf ball before they collided

C:half the velocity of Edwin’s golf ball before they collided

D:equal to the velocity of Edwin’s golf ball after they collided

Answer 1

Answer: A

Step-by-step explanation:

Because of the law of conservation of momentum (total momentum of two golf balls must be constant).
