Do not solve the full qn My question is why is the vector VAot = 1.5 and VAon =-2.6 as shown in the solution. I understand VAot is = -3cos30=-1.5 and VAon = -3sin30 =-2.6 Why is it postive 1.5 instead of negative 1.5 or for VAon why isit negative 2.6 and not positive 2.6? Why is Vb1t = -0.866 and not 0.866 and Vb1n = -0.5 and not 0.5. I dont get it how to visualise the vector direction. Please use a vector diagram with the angles to illustrate

Question
Do not solve the full qn
My question is why is the vector VAot = 1.5 and VAon =-2.6 as shown in the solution. I understand VAot is = -3cos30=-1.5 and VAon = -3sin30 =-2.6
Why is it postive 1.5 instead of negative 1.5 or for VAon why isit negative 2.6 and not positive 2.6?
Why is Vb1t = -0.866 and not 0.866 and Vb1n = -0.5 and not 0.5. I dont get it how to visualise the vector direction.
Please use a vector diagram with the angles to illustrate it.
![4. A sphere A of mass m= 2 kg is released from rest in the position shown
and strikes the frictionless inclined surface of a wedge B of mass m3= 6 kg
with a velocity v,= 3 m/s. The wedge, which is supported by rollers and
may move freely in the horizontal direction, is initially at rest. Knowing
that 0 = 30° and that the coefficient of restitution between the sphere and
the wedge is e = 0.80, determine the velocities of the sphere and of the
wedge immediately after the impact.
