At the highest point, the projectile has only horizontal momentum. When it explodes, the total horizontal momentum must remain conserved. Since the two parts have equal mass, their horizontal velocities must be equal in magnitude but opposite in direction. One part has a horizontal velocity of -30 m/s (negative because it's moving downward). To conserve momentum, the other part must have a horizontal velocity of +30 m/s. Therefore, the correct answer is (d) 30 m/s.
