Question

B. Boat travels north then west

A boat travels 76.0 km due north in 8.0 hours then 56.0 km due west in 5.0 hours.
The magnitude of the average velocity (to 2 decimal places) of the boat (in km/h) in the 8 + 5 hour period is

Answer 1

Step-by-step explanation:

θ = arctan(56.0/76.0) = 36.4° West of North

average velocity is √(56.0² + 76.0²) / (8 + 5) = 94.4/13 = 7.26 m/s
