2. A swimmer has a swimming speed of 3.8 m/s in still water. When they head directly across a river, they end up travelling downstream at an angle of 72° to the shore. Include a labelled vector diagram for each part. (8 marks) a) What is the speed of the current? b) What heading would the swimmer need to have in order to reach a point directly across the river? Unit 1 Motion in a Plane Test Page 1 of 3 c) If the stream is 12 m wide, how long would a trip directly across the river take?
