3. Tomemos

  1. Tomemos θ\theta como o ângulo que o vetor A\vec{A} forma com o eixo +x+x, medido no sentido anti-horário desse eixo. Determine o ângulo θ\theta para um vetor que possiu os seguintes componentes: a) Ax=2,0 m,Ay=1,0 mA_{x}=2,0 \mathrm{~m}, A_{y}=-1,0 \mathrm{~m}; b) Ax=2,0 m,Ay=1,0 mA_{x}=2,0 \mathrm{~m}, A_{y}=1,0 \mathrm{~m}; c) Ax=A_{x}= 2,0 m,Ay=1,0 m;-2,0 \mathrm{~m}, A_{y}=1,0 \mathrm{~m} ; d) Ax=2,0 m,Ay=1,0 mA_{x}=-2,0 \mathrm{~m}, A_{y}=-1,0 \mathrm{~m}
