Three 70-kg deer are standing on a flat 200-kg rock that is on an ice-covered pond. A gunshot goes off and the dear scatter, with deer A running at (15 m/s)i ^ + (5.0 m/s)j ^ , deer B running at (−12 m/s)i ^ + (8.0 m/s)j ^ , and deer C running at (1.2 m/s)i ^ − (18.0 m/s)j ^ . What is the velocity of the rock on which they were standing?
