1. A boat can be rowed at Think & Prepare 1. In all the questions below, think about motion from the point of view of an observer on the boat and the point of view of an observer on the shore. BW = 8.5 km/h in still water. (a) How much time is required to row 1.2 km downstream (East) in a river moving ws = 3.8 km/h relative to the shore? Time required to row 1.2 downstream = (b) How much time is required for the return trip? Time for the return trip = min (c) In what direction must the boat be aimed to row straight across the river? Express the angle in degrees measured West of North. vws VBW min 0 VBS Direction of boat = ° West of North. (d) Suppose the river is 1.2 km wide. What is the velocity of the boat with respect to shore and how much time is required to get to the opposite shore? VBS km/hr
