What are the components of vector A if its magnitude is 70 m/s and makes an angle of 51.7° with the +x-axis?
1 answer:
Since, A is a vector. Hence, we can break it into two components (x and y)
Angle made by the velocity vector A with the x-axis = 51.7°
Magnitude of the vector A = 70 m/s
°
![A_x = 70 \times 0.617](https://tex.z-dn.net/?f=A_x%20%3D%2070%20%5Ctimes%200.617)
m/s
°
![A_y = 70 \times 0.784](https://tex.z-dn.net/?f=A_y%20%3D%2070%20%5Ctimes%200.784)
m/s
Hence, the option C is correct.
