Mechanics question. I've had 4 different answers from 4 different people and am still none the wiser to this teaser.
A river flows North to south. A rower on the lefthand bank (call this 0 , 0) facing north spots an object. The object is at 50sin20 (co ords 17.1 , 47). The current is running south at 3m/s. The rower can maintain a rowing speed of 4m/s. The current will affect both rower and object.
Calculate the direction with respect to the riverbank the rower must row in order to intecept the object.
