Vector Practice & Motion in 2D 30% 1. Use the 60° angle to find Vox= 20⁰ 70° 60⁰ a= 2 m/s² Voy= 2. Use the 30° angle to find Vox= Voy= 3. Use the 70° angle to find Ox= ay= 4. What is the velocity vector after 2 seconds? Express the velocity as a magnitude and a direction. (Ans:Vox Vocos 60°-2.5 m/s, Voy-Vosin 60°-4.3 m/s; Vox-Vosin 30º=2.5 m/s, Voy=Vocos 300-4.3 m/s; a=-1.9 m/s² ,ay=-0.68 m/s2, after 2 seconds V=-1.3 m/s, Vy-2.9 m/s, V= 3.2 m/s at 66 degrees north of west) I V = 5 m/s
