    Answer:

    The magnitude of their combined momentum after the collision  is 26 kg-m/s.

    Explanation:

    Given that,

    Two dogs, Rover and Fido, run on a level frictionless surface.

    Rover runs eastward with a momentum of 24 kg-m/s and Fido runs northward with momentum 10 kg-m/s. We need to find the magnitude of their combined momentum after the inelastic collision.

    For inelastic collision, momentum remains conserved. The net momentum is given by :

    p=\sqrt{p_1^2+p_2^2} \\\\p=\sqrt{24^2+10^2} \\\\p=26\ kg-m/s

    So, the magnitude of their combined momentum after the collision  is 26 kg-m/s. Hence, this is the required solution.
