Question

A cruise ship sails due south at 2.50 m/s while a coast guard patrol boat heads 19.0° north of west at 4.80 m/s. What are the x-component and y-component of the velocity of the cruise ship relative to the patrol boat? (Assume that the +x-axis is east and the +y-axis is north. Enter your answers in m/s.)

    Answer:

    Explanation:

    We shall represent the velocity of cruise ship and coast guard petrol boat in vector form .

    velocity of cruise ship

    Vcs = – 2.5 j

    Vpb =  – 4.8 cos 19 i + 4.8 sin 19 j = – 4.54 i + 1.56 j

    velocity of the cruise ship relative to the patrol boat

    = Vcs – Vpb

    =  – 2.5 j – ( – 4.54 i + 1.56 j  )

    =  – 2.5 j  +  4.54 i –   1.56 j  

    = 2.04 i – 1.56 j .

    x-component of the velocity of the cruise ship relative to the patrol boat

    = 2.04 m /s

    y-component of the velocity of the cruise ship relative to the patrol boat

    = – 1.56 m /s .
