Question

I need to get magnitude of Ax and Ay, Bx and By. total resultant and direction of resultant

Answer 1

• Angle between vectors=180-45=135°

Now

`\\ \tt\longrightarrow R=√(A^2+B^2+2ABcos\theta)`

`\\ \tt\longrightarrow R=√(92^2+34^2+2(92)(34)cos135)`

`\\ \tt\longrightarrow R=√(8464+1156+6256(-0.7))`

`\\ \tt\longrightarrow R=√(9620+4379)`

`\\ \tt\longrightarrow R=√(13999)`

`\\ \tt\longrightarrow R=118.3N`
