Question

You are on a cruise ship traveling north at a speed of 13 m/s with respect to land. 1)If you walk north toward the front of the ship, with a speed of 3.2 with respect to the ship, what is your velocity with respect to the land?2)If you walk south toward the back of the ship, with a speed of 3.2 with respect to the ship, what is your velocity with respect to the land?)your friend is sitting on another cruise ship traveling south at 14 m/s. As you walk toward the back of your ship at 3.2 m/s, what is your velocity with respect to your friend?

Answer #1

Here ,

speed of ship , vs = 13 j m/s

1)

speed of person , v1 = 3.2 j m/s

velocity relative to land = vs + v1

velocity relative to land = 13 + 3.2

velocity relative to land = 16.2 j m/s

the velocity relative to land is 16.2 m/s in the north direction

2)

speed of person , v1 = - 3.2 j m/s

velocity relative to land = vs + v1

velocity relative to land = 13 - 3.2

velocity relative to land = 9.8 j m/s

the velocity relative to land is 9.8 m/s in the north direction

3)

for speed of friend , vf = -14 m/s

velocity relative to friend = v - vf

velocity relative to friend = 9.8 - (-14)

velocity relative to friend = 23.8 m/s

the velocity relative to friend is 23.8 m/s in north direction

A person going for a morning jog on the deck of a cruise ship is
running toward the bow (front) of the ship at 2.0 m s while the
ship is moving ahead at 8.5 m s. What is the velocity of the jogger
relative to the water? Later, the jogger is moving toward the stern
(rear) of the ship. What is the jogger’s velocity relative to the
water now?

An cruise ship passes through a shoreline that is 204 m long. It
enters with an initial speed of 24 m/s and decelerates at a rate of
0.11 m/s2 as it goes through.
a. During what time interval, is the front of the cruise ship
within the shoreline?
b. How fast is the ship moving when its front leaves the
shore?
c. If the ship is 134 m long, how long after the front of the
ship enters the shoreline...

A person going for a morning jog on the deck of a cruise ship is

Uther Undlethwaite, the unremarkable pirate, paced the deck of
his pirate ship. The ship was sailing 0.62 radians North of East at
a speed of 13 m/s with respect to the water. The water water was
moving at a speed of 2 m/s (relative to the sea floor) directly
North. Uther walked 1.26 radians South of West at a speed of 1 m/s.
What was Uther's speed relative to the sea floor?

You are traveling on an airplane. The velocity of the plane with
respect to the air is 170 m/s due east. The velocity of the air
with respect to the ground is 46 m/s at an angle of 30° west of due
north. What is the heading of the plane with respect to the ground?
(Let 0° represent due north, 90° represents due east).
