What is the height of the wedge?

[imdiskid06]

A small block of mass .5kg is released form rest at the top of a curved-shaped frictionless wedge of mass 3 kg , which sits on a frictionless horizontal surfces. When the block leaves the wedge, its velocity is 4 m/s to the right. Find the velocity of the wedge after the block reaches the horizontal surface. What is the height of the wedge?

You should really show some of your working / thoughts. Hint: Use circular motion and think about normal reaction forces.

Alternatively, you can use the work-energy theorem.

The work energy theorem is probably simpler.
