A small block of mass $77g$ is released from rest at the top of a curved frictionless wedge of mass $354g$ which sits on a frictionless horizontal surface as shown.

The acceleration due to gravity is $9\mathrm{.}81\frac{m}{s^2}.$ Right is the positive direction.

When the block leaves the wedge, its velocity is $2\mathrm{.}84\frac{m}{s}$ to the right.

What is the velocity $v_b$ of the wedge after the block reaches the horizontal surface?

Answer in units of $\frac{m}{s}.$

What is the height $h$ of the wedge? Answer in units of $m.$
