I uploaded my question below; basically I am confused in part b) where they show that:
50 kgm/s = (5kg)v2 - (5kg)(-4m/s) then they say that
30 kgm/s = 5kg v2, but shouldn't it be 70 kgm/s = 5kg v2?
As noted at the beginning of the question North is positive and thus since the cart moves south is negative (-4m/s).
Could this be a typo ?
