WebUsually, though, in simple cases like this we just say that the momentum is '8.0 kg-m/s' with the positive sign understood. If the object was moving toward the left with a velocity of -4.0 m/s, then the momentum would be -8.0 kg-m/s, and you would say 'negative 8.0 kg-m/s'. Momentum problems can become more complicated, however. Web18 okt. 2013 · Professor walter lewin is correct. Let's do the elastic case. The ball momentum changes by -2mv. The momentum of the wall must change by 2mv due to momentum conservation. Assuming that the wall was initially at rest, the speed of the wall will be V w = 2mv/M w. It's kinetic energy will be K w = (1/2) M w V w 2 = (1/2) M w …
