It is usually assumed that "small angular displacement" means all angles between -15º and 15º. The formula for the pendulum period is T = 2π√(L/g)

You'd be much better off with momentum; you would want to calculate the momentum of the pendulum, right before the impact, and then apply conservation of momentum, which does give you the subsequent motion of the impact.
