Answer:

600 m/s

Step-by-step explanation:

Energy is conserved from (b) to (c).

½ (M + m) V² = (M + m) g h

V² = 2gh

V² = 2 (9.8 m/s²) (0.45 m)

V = 2.97 m/s

Momentum is conserved from (a) to (b).

mv = (M + m) V

(0.015 kg) v = (3.0 kg + 0.015 kg) (2.97 m/s)

v = 597 m/s

Rounding, the ball is fired at 600 m/s.
