A person going for a morning jog on the deck of a cruise ship is running toward the bow (front) of the ship at 2.2 while the ship is moving ahead at 6.8 .

1. What is the velocity of the jogger relative to the water?

2. Later, the jogger is moving toward the stern (rear) of the ship. What is the jogger's velocity relative to the water now?

god knows

haha this one had me stuck for a while as well, but it is really easy. All you have to do is add the two velocitys for the first answer (because if the ship is moveing 6.8 m/s and you are running with the ship then you will add 2.2 m/s and you will get your answer.) and if you are running against the ship (opposite direction of where the ship is going) then you would simply subtract.

i have a question

A person going for a morning jog on the deck of a cruise ship is running toward the bow (front) of the ship at 2.1 m/s while the ship is moving ahead at 5.6 m/s .

who knows

To answer both questions, we need to take into account the velocity of the jogger and the velocity of the ship. The velocity of an object is relative to the reference point or observer, in this case, the water.

Let's assume the positive direction is towards the front of the ship, and the negative direction is towards the back.

1. To find the velocity of the jogger relative to the water while running towards the bow (front), we need to subtract the velocity of the ship (6.8 m/s) from the velocity of the jogger (2.2 m/s). Since both velocities are in the same direction (towards the front), we subtract them:

Velocity of the jogger relative to the water = Velocity of the jogger - Velocity of the ship
= 2.2 m/s - 6.8 m/s
= -4.6 m/s

The negative sign indicates that the jogger is moving in the opposite direction of the ship.

2. When the jogger is moving towards the stern (rear) of the ship, the velocities are in opposite directions. In this case, we need to add the velocities:

Velocity of the jogger relative to the water = Velocity of the jogger + Velocity of the ship
= 2.2 m/s + (-6.8 m/s)
= -4.6 m/s

Again, the negative sign indicates that the jogger is moving in the opposite direction of the ship.
