1. A boat can be rowed at Vow = 8 km/h in still water. 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. (a) How much time is required to row 1-8 km downstream (East) in a river moving Vws = 3.2 km/h relative to the shore? Time required to row 1.8 downstream = V min (b) How much time is required for the return trip? Time for the return trip = V 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 VEW A VBS Direction of boat = West of North. (d) Suppose the river is 1-1 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? VES = = V km/hr Time required to get to the opposite shore = min (e) Suppose, instead, the boat is aimed straight across the river. How much time is required to get across and how far downstream is the boat when it reaches the opposite shore? VWS V BW A VBS Time required to get to the opposite shore heading straight = min Distance downstream = V km
