Problem: Two boats are heading away from shore. Boat 1 heads due north at a speed of 3.9 m/s relative to the shore. Relative to Boat 1, Boat 2 is moving 35° north of eastat a speed of 1.5 m/s. A passenger on Boat 2 walks due east across the deck at a speed of 1.4 m/s relative to Boat 2.
Part A: What is the speed of the passenger relative to the shore?
I need help to determine the speed of the passenger relative to the shore.
