A passenger on a boat moving at 1.13 m/s on a still lake walks up a flight of stairs at a speed of 0.50 m/s, Fig. 3-44. The stairs are angled at 45° pointing in the direction of motion as shown. What is the velocity of the passenger relative to the water? I have to get the magnitude of it and I get -123 which isfor sure not right I also have to get the direction in degrees---- how do I do that. My teacher hasn't taught us all of this yet!
