Name: ACI: SPH3U 2D Kinematics 16. A boat's speed is 2.70 m/s in still water. If the boat points its prow directly west across the stream, with a current of 1.10 m/s [N], what is the velocity of the boat relative to the shore? 17. A jetiski heads directly across a river at 11.0 m/s [S]. If the river is owing west at 4.5 m/s. a. Determine the jetiski's velocity relative to the shore. b. If the river is 735 m wide, how long will it take to cross the river? (3. How far downstream will the jet-ski land? Page 15 of 24
