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? Are you able to show in a vector diagram

My question is why is the vector VAo= 1.5 and VAon =-2.6 as shown in the solution. I understand VAois = -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? Are you able to show in a vector diagram 

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.
