# Wedge problem

The system is released from rest. Calculate the speed of wedge (in $$\text{ms}^{-1}$$) when block reaches the bottom of the wedge.

Details and assumptions:

• Wedge is movable

• Mass of wedge is twice the mass of block

• The height of the wedge is 20 meters

• The angle of inclination is $$30 ^\circ$$

• Take $$g = 10 \, \text{ms}^{-2}$$

• All the surfaces are smooth
