Concept explainers

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.

Question

A sailor is enjoying a nice day on his sailboat,
sailing west with the wind at constant velocity. At
one point the sailor spots an anchored buoy some
distance to the east of the boat, and turns on his
motor to head towards it. The boat kept gliding to
the west for some distance before turning around
and heading eastward.
The boat was traveling initially with velocity v =
-6.0i m/s and it took the the boat 2.0 s to turn
around. What is the velocity of the boat, 5.0 s
after the motor is turned on?
The coordinate system is set up such that the +i
direction is East.
Pick the correct answer
O +3.0î m/s
O -9.0i m/s
O -3.0î m/s
o +9.0å m/s
o +2.0i m/s

The velocity of the wind relative to the water is crucial to sailboats. Suppose a sailboat is in an ocean current that has a velocity of 2.1 m/s in a direction 27° east of north relative to the Earth. It encounters a wind that has a velocity of 4.4 m/s in a direction of 49° south of west relative to the Earth. 1. What is the magnitude of the velocity of the wind relative to the water, in meters per second? 2. What is the angle of the velocity of the wind relative to the water degrees south of west?
