Homework Statement
A wheel drive in the horizontal plane with angular velocity 13 rad / s. Two bodies mass mA = 1 kg and mB = 1.4 kg slide without friction along a rail fixed to the disk and passing through its center. The two bodies are connected by a bar inextensible (negligible mass) and 0.3m long.
Knowing that the body A is initially 15 cm from the center, determine the initial radial velocity that should print the body so that his movement tends to break even.
Homework Equations
aA = xA w^2 - (mB l w^2) / (mA+mB)
xA(eq) = (mBl/(mA+mB))
The Attempt at a Solution
I determine the equations above, but I don't how to use them to calculate what I need to...
Te correct answer is 0,325 m/s
