A student is riding a bicycle at a speed of 5.0 m/s heading north when he collides with another student on a bicycle heading east. The first student and his bicycle have a mass of 80 kg, while the second student and his bicycle have a mass of 60 kg. The two bicycles get entangled and slide to a stop, leaving skid marks on the ground at an angle of 42° north of east from the point of collision.
