You go for a short walk traveling in three stages. The first displacement is 58.5 m 20.0 degrees east of north. The second displacement is 78.0 m 40.0 degrees south of east. Finally you go 99.0 m 17.0 degrees north of west. The answer I got was 36.9 m, 66.2 degrees north of west,which is correct. But then they ask: If this trip took 125 seconds, what was the average velocity? They give the answer: 0.295 m/s, 66.2 degrees north of west. What I got for that answer was 1.884 m/s. I figured you could just use the V avg = total displacement over time equation. So 58.5 + 78 + 40 / 125 = 1.844. What am I doing wrong here? Thanks for the help!!
