A wagon with mass M can move on frictionless surface. A mathematical/ideal pendulum is fastened on the wagon. At the initial moment the wagon and the pendulum were at rest and the pendulum makes an angle of x with the vertical. What will be the velocity of the wagon when the pendulum makes an angle of y with the vertical?

2. Relevant equations

I guess its a linear momentum question but I dunno the equation.

3. The attempt at a solution
