a.) How long does it take for the book to reach the elevator floor, 1.4 m below your arm?
b.) What is the book's speed relative to you when it hits the elevator floor?

2.) A passenger walks from one side of a ferry to the other as it approaches a dock. If the passenger's velocity is 1.80 m/s due north relative to the ferry, and 4.5 m/s at an angle of 32.0 degrees west of north relative to the water, what are the direction and magnitude of the ferry's velocity relative to the water
_____ degrees west of north
_____ m/s
