Two projectiles are projected with same velocity at same angle, one on the earth and second on the moon. If the projectile acquires the maximum height of H on the earth, then what will be the maximum height attained by the projectile on the moon?

Maximum height attained by the projectile on the earth is,

Acceleration due to gravity on the moon is g/6. Therefore maximum height attained by the projectile on the moon is,

Thus maximum height attained on the moon is six times the maximum height attained on the earth.
