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?

Physics

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 = A \times Cos 51.7°

A_x = 70 \times 0.617

A_x = 43.4 m/s

A_y = 70 \times Sin 51.7°

A_y = 70 \times 0.784

A_y = 54.9 m/s

Hence, the option C is correct.
