Answer (2)
The velocity of the **passenger **relative to the water is the sum of the motion due to the boat and the component of the motion up the stairs in horizontal (i) and vertical (j) directions. This gives the vector as (1.70 m/s + 0.60 * 0.71)m/s i + (0.60 * 0.71) m/s j. ;
The vector velocity of the passenger walking up the stairs relative to the water is approximately v passenger = 2.1 i + 0.42 j . This result accounts for the movement of the boat and the passenger's walking direction. The total horizontal component is 2.1 m/s, while the vertical component is 0.42 m/s.
