Answer:
42.96 km/s
Explanation:
From the conservation of Energy

Mass gets cancelled

 = Escape velocity of Earth = 11.2 km/s
 = Escape velocity of Earth = 11.2 km/s
 = Velocity of projectile = 44.4 km/s
 = Velocity of projectile = 44.4 km/s

The velocity of the spacecraft when it is more than halfway to the star is 42.96 km/s
