Answer:
42.96 km/s
Explanation:
From the conservation of Energy
Mass gets cancelled
= Escape velocity of Earth = 11.2 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
It depends on both of them.
In fact, the projectile begins its motion with an initial velocity of
and an angle of 
. On the y-axis (vertical direction), it is an accelerated motion with acceleration equal to -g (gravitational acceleration). The vertical velocity of the projectile at any time t is given by
and as it can be seen, this depends on both initial velocity and angle.
