When the striker hits the queen perpendicularly at the center (impact parameter = 0), the collision is head-on. The queen's post-collision velocity is determined by the conservation of momentum and the coefficient of restitution (e), which defines the elasticity of the collision. The formula is:
Since the impact parameter is zero, the outcome depends only on the masses and the coefficient of restitution, not on size or surface roughness.
Final Answer: masses of striker & queen and coefficient of restitution
