(a) Conservation of linear momentum requires Mv m v m v m v G G G H 01 12 23 3 =++ , which (using the above information) leads to 33 3 ˆˆ (1.00 10 i 0.167 10 j) m/s v × G . The magnitude of G v 3 is 22 3 3 (1000 m/s) ( 167 m/s) 1.01 10 m/s v =+ = × . It points at θ = tan –1 (–167/1000) = –9.48° (that is, at 9.5° measured clockwise from the + x axis).
