Pоint B mоves relаtive tо point A аccording to the below equаtion: v B / A = ( 3 i ^ + 2 j ^ ) m/s {"version":"1.1","math":"v_{B/A}=left(3widehat{i}+2widehat{j}right)text{ m/s}"} Point A moves with an absolute velocity according to the below equation: v A = ( 7 i ^ + 1 j ^ ) m/s {"version":"1.1","math":"v_{A}=left(7widehat{i}+1widehat{j}right)text{ m/s}"} Determine the absolute velocity of point B (give your answer in vector form).
