yes by absolute velocity i mean linear velocity.
well I know that if point A was fixed, than Va = Woa x Rao. But since it is moving, Va = Woa x Rao + Vrel. I assume that Vrel is tangent to point A in the direction: 1.255i + 2.18j. and yes angular velocity is clockwise.
Homework Statement
W(oa) = -5k
α(oa) = 3k
B = 30 deg
B(dot) = -2cos 30i + 2sin30j = Vrel
b(double dot) = 4cos30i - 4sin30j)
Homework Equations
Va = Woa x Rao + Vrel
