Naughty and active Xiaoming traveled to Long Island by boat with his parents. When he came to the boat, he jumped with joy (pictured). Because the ship is moving, so

(1) When the ship is moving in the water, people are also moving. When people jump vertically on the boat, they must fall back to their original position, because the inertial person must keep the original movement.

(2) When Xiao Ming falls on the deck, his feet will feel pain, because the forces are mutual, and Xiao Ming's feet will be affected by a force exerted by the deck.

So the answer is: after Xiao Ming jumps, he will go forward with the ship, because inertia will fall back to its original place; The action of force is mutual.
