Question

A canoe is paddled downstream with a speed of 1.9m/s relativeto the water. The river current has an average speed of 1.6m/s.Afly is walking on the canoe at a speed of 0.5m/s relative to thecanoe. Determine the fly's velocity relative to the riverbanks ifit walk...(downstream is pos.) A) towards the front of the canoe B) towards the back of the canoe A canoe is paddled downstream with a speed of 1.9m/s relativeto the water. The river current has an average speed of 1.6m/s.Afly is walking on the canoe at a speed of 0.5m/s relative to thecanoe. Determine the fly's velocity relative to the riverbanks ifit walk...(downstream is pos.) A) towards the front of the canoe B) towards the back of the canoe

Explanation / Answer

    Velocity of Canoe relative to water, V1 = 1.9m/s     Velocity of river current, V2 = 1.6 m/s     Velocity of Canoe relative to river bank , V =V1 + V2                                                                       = 3.5 m/s     Velocity of fly relative to Canoe, Vf = 0.5m/s (a)     Velocity of fly relative to riverbank = Vf + V =4 m/s (b)     Velocity of fly relative to riverbank = -Vf + V= 3.5 m/s
