Conservation of linear momentum applies to the embedding process. Use that to calculate the velocity at impact, before swinging begins.
Then use that velocity and conservation of energy to calculate how high it swings.
V = sqrt (2 g H) and the height that is reaches is
H = L (1 - cos A)
Use that to solve for the maximum incination angle A
