Question

A small block of mass mi is released from rest at the top of a curve-shaped, frictionless wedge which sits on a frictionless horizontal surface as shown. The height of the wedge is h = 5 m. When the block leaves the wedge its velocity relative to the ground is measured to be 4.00 m/s to the right as shown in the figure. If the mass of the block is doubled to become 2m, what will be its speed when it leaves the wedge? 4.00 m/s (a) (6)
