Name: ACI: SPH3U 2D Kinematics > A boat has a velocity of 4.0 m/s [E] in still water. It is in a river of width 150 In, that has a river velocity of 3 m/s [N]. a) What is the velocity of the boat relative to the shore? b) How far downstream did the boat travel? c) How long will it take to cross the river? > The same boat, which has a velocity of 4 m/s, travels directly across the 150 m wide river which has a current of 3 H115 [N]. a) What is the speed of the boat crossing the river? b) What is the heading of the boat? c) How long will it take to cross .he river?
