Need Some Help With Displacement...plz =) I'm working independently on Grade 11 Physics, and ran across a displacement question I need some help with. So here goes: 1. Jessie drove north at 45km/h for 20 min, then turned West and drove at 54km/h for 27min. Finally she drove South at 18km/h for 6.4 min. Find her displacement 2. According to my notes Displacement= the difference from final position to initial position The final answer according to the book is 28km[W 28degrees N] but I have no idea how to get this answer. Any help would be GREATLY appreciated. Thanks!
