Acruise ship is moving at constant speed through the water. the vacationers on the ship are eager to arrive at their next destination. they decide to try to speed up the cruise ship by gathering at the bow (the front) and running together toward the stern (the back) of the ship.(a) while they are running toward the stern, what is the speed of the ship? 1.higher than it was before they started running

2. unchanged from what it was before they started running

3. lower than it was before they started running

4. impossible to determine

1. higher than it was before they started running

Explanation: As the vacationers run towards the back(stern) of the ship the exerting more pressure against the pressure exerted by the wave supporting the moving ship,the pressure exerted on the moving ship will be increased, leading to a slight increase in the speed of the ship compared to the speed before they started running towards the back(stern) of the ship.
