A boat propelled so as to travel a speed 0.5m/s in still water , moves directly(in a straight line) across a river that is 60m wide. The river flows with a speed of 0.3 m/s .How long in seconds does it take the boat to cross he river?
what about resolving the velocity into vector
oh yeah,sorry, i took this problem as one of those math ones, yup, we'll do this by vectors
