1. The eye of a hurricane passes over Grand Bahama Island in a direction 30.0° north of west with a speed of 42.0 km/h. The hurricane goes this direction for three hours. Then the course of the hurricane suddenly shifts due north. From this point, its speed is 27.0 km/h for two more hours. Convert the velocity vectors to position vectors. Write the position vectors as a magnitude and angle. (remember to measure the angles from the positive x axis) 30°N/w O - 180° 30 150° 42 Kmh * 3h= 136km * 3h= 126とm %3D Y2 a7km/h x 2h:54km doplacoment NoRth b. Assuming Grand Bahama Island is at (0,0), draw a sketch of the two position vectors representing the path of the hurricane. Remember that North is the positive y axis and that east is the positive x axis. Vz - 54 Km 30 W--- O, 0 Determine the components of each of the two position vectors.

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.
