This has stumped me for a while:
Rower A is stationary at point A adjacent to the river bank when he spots an object (O) floating down the river. He estimates that the object is 50m away and heading south at a speed of 3m/s (the same speed as the river)
Question says:
Assuming Rower A can sustain a rowing speed of 4m/s
i) Draw the diagram of the velocity vectors involved if Rower A is to intercept the object?
ii) Calculate the direction with respect to the riverbank he needs to row (in degrees) in order to achieve his goals?
I understand that the object is going to be constantly moving down the river, but dont know how to work this one out?
