9. A 0.500 kg ball with a speed of 4.0 m/s strikes a stationary 1.0 kg target. The ball and target

stick together. If momentum is conserved, what is the total momentum of the ball and target
after the collision?
A. 0.0 kgm/s
B. 0.5 kgm/s
C. 1.0 kgm/s
D.2.0 kgm/s​

Answer:

D. 2.0 kg m/s

Explanation:

Momentum after = momentum before

p = (0.500 kg) (4.0 m/s) + (1.0 kg) (0 m/s)

p = 2.0 kg m/s
