Asked by Alyssa
A motorboat whose speed in still water is 2.91 m/s must aim upstream at an angle of 30.0 degrees (with respect to a line perpendicular to the shore) in order to travel directly across the stream.
- What is the speed of the current?
- What is the resultant speed of the boat with respect to the shore?
