a) The constant speed of kayak paddler in still water is 0.4 m/s. The paddler needs to cross a 490 m wide river and arrive at the opposite side zero meters down stream from the starting point. The paddler accomplishes this by steering the craft 27 degrees upstream. Determine the crossing time in sec. b) Heavy rain causes the river flow rate to increase 22 %. The paddler repeats the crossing at the same speed with respect to still water and the same steering angle from Problem 10 and arrives at the opposite side some distance down stream from the starting point. How far downstream is this landing? c) The under the increased flow conditions in Problem 11, the same paddler repeats the crossing with the same steering angle and arrives at the opposite side zero meters downstream from the starting point. Determine the speed of the kayak in m/s as measured from a stationary drone high above.

    A swimmer heads directly across a river, swimming at her maximum speed of 1.60 m/s relative to the water. She arrives at a point 40.0 m downstream from the point directly across the river, 67.0 m wide. In what direction (as an angle relative to a direct line across the river) should the swimmer aim instead, so that she arrives at the point directly opposite her starting point?

    You attempt to swim across a river 120 meters wide, and can swim at 2.6 m/s in still water. You set off aiming to arrive a point 50 meters downstream of your starting point. However, you fail to take into account the flow of the water, and because of this you land on the opposite bank 100 meters downstream of your starting point. What is the speed of the flow of water, in m/s?
