2-Dimensional Motion

  1. Oct 14, 2007 #1
    1. The problem statement, all variables and given/known data
    A passenger on a boat moving at 1.25 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?

    Magnitude = ___m/s
    Direction= ___° (above the water)

    Could someone please help me with this problem... I've been stuck on it all night, and can't seem to figure out the correct method of solving it... Help would be greatly appreciated... Thanks =)

    Not sure without the picture. But it seems like a vector addition problem. The velocity of the passenger wrt water, is the vector sum of:

    the velocity of the boat wrt water + the velocity of the passenger wrt the boat.
