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...
