color(purple)(V_x = -6.8933, V_y = 2.3294, tan (theta) = - 0.2679Vx=6.8933,Vy=2.3294,tan(θ)=0.2679

Explanation:

enter image source here

r = -9, theta = (23pi)/12r=9,θ=23π12

V_x = -9 * cos ((23pi)/12) = -8.6933Vx=9cos(23π12)=8.6933

V_y = -9 * sin ((23pi)/12) = 2.3294Vy=9sin(23π12)=2.3294

tan theta = tan ((23pi)/12) = -0.2679tanθ=tan(23π12)=0.2679
