Question 7 (10 points) A swimmer would like to cross a 0.55 km wide river. The current is 1.8 m/s. The swimmer wants to land directly across the river. Unfortunately, the swimmer does not have a good understanding of physics and guesses the direction. The swimmer heads upstream at 45" at a constant speed of 3.0 m/s. a) Clearly show the swimmer did not land directly across from their starting point. b) How far upsteam/downstream did the swimmer miss by? c) What heading should they take next time to get directly across
