Sophia (mass 47Kg) is travelling to the right with a velocity of 7.2m/s and ​Neesha (mass 68Kg) is travelling to the left with a velocity 4.8m/s. When ​they meet, they hold hands and travel off together. Give their final ​velocity and direction

We know that p=mv, So Sophia travels at 7.2 m/s and she has a mass of 47kg so her p is: p=7.2 x 47=338.4 kgm/s Neesha travels with a velocity of -4.8 m/s and she has mass of 68kg, so her p is: p= -4.8 x 68= ...
