A ball of mass 0.20 kg hits a wall at right angles at 6.0 m/s. The ball rebounds from the wall at 4.0 m/s. What is the magnitude of the change in momentum of the ball?
0.40 kg m/s0.40\ \text{kg m/s}0.40 kg m/s
1.2 kg m/s1.2\ \text{kg m/s}1.2 kg m/s
2.0 kg m/s2.0\ \text{kg m/s}2.0 kg m/s
10 kg m/s10\ \text{kg m/s}10 kg m/s
