You can use the formula A=F/M, the rate that it is being accelerated upward is 3.3, so about 3.
The mass of the basket = weight/acceleration due to gravity. (75/10=7.5 kg)
100 (upward force from girl) minus 75 (downward force from basket) is 25.
So 25=7.5a, which becomes 25/7.5, which equals 3.33 kg x m/s.
And when rounded, the momentum is about 3, (or 3 p).
Hope this helps!
