Question

A boat travels down a river. Relative to the riverbank, the water moves at a constant speed of 22 m/s in a direction of 60° NW. A woman on the boat drops a flask into the river. After 1.2 seconds, the woman noticed the flask, moving with the water, had traveled 18 m in a direction of 20° SE.

 

A REMINDER: A velocity is a magnitude and direction

Relative to the riverbank, what is the velocity of the boat?

Draw a bird’s eye view, from the boat’s perspective, displaying the other objects velocities (The water, the riverbank, and the flask)
