Momentum A ball weighing .05 kg strikes a 1000 kg stationary wall at 30

m/s. According to Newton's Third Law, which of these must

be true?

Select one:

The total momentum of the system after impact is 30000 kg • m/s

The total momentum of the system before impact was 15 kg. m/s

The wall moves away from the ball at 30 m/s.

The total momentum of the system before impact was 1.5 kg . m/s
