Answer 1

Answer:

Let v be the velocity of the girl on the cart as the cart starts moving.

The total momenta of the girl and cart before the interaction = (50 x 5 m s-1) + (4 x 0 m s-1)

                                                                            = 250 kg m s-1

The total momenta after the interaction = (50 + 4) kg x v m s-1

                                                               = 54 v kg m s-1

According to the law of conservation of momentum,

Total momentum before the interaction = Total momentum after the interaction

→ 54 v = 250
