    1. The problem statement, all variables and given/known data
    A 63-kg student stands on a 34-kg cart that is free to move in any direction. The cart and student are moving together with a velocity of 3.2 m/s [W]. The student then starts to walk so that her velocity is 1.8 m/s [25° W of N] relative to the floor. Calculate the new velocity of the cart.


    2. Relevant equations
    p=mv


    3. The attempt at a solution
    i dont know what is going on
