Ship (A ) is located 4 km north and 3 km east of ship (B ). Ship (A ) has a velocity of (20 kmh ⁻¹ ) towards the south and ship (B ) is moving at (40 kmh ⁻¹ ) in a direction (37^ ) north of east. (X ) and (Y )-axes are along east and north directions, respectively.

Options

  1. AVelocity of (A ) relative to (B ) is (-32 i -44 j )
  2. BPosition of (A ) relative to (B ) as a function of time is given by ( r _ A B =(3-32 t) i +(4-44 t) j )
  3. CVelocity of (A ) relative to (B ) is (32 i -44 j )
  4. DPosition of (A ) relative to (B ) as a function of time is given by ((32 t i -44 t j ) )

Correct answer

B. Position of (A ) relative to (B ) as a function of time is given by ( r _ A B =(3-32 t) i +(4-44 t) j )

Step-by-step solution

Both options ' (a ) ' and ' (b ) ' are correct. This indicates that multiple conditions or descriptions are valid for the given scenario in the question.
