Imagine you go for a jog in the local park in your neighborhood heading eastward (from west to east, let's say east is positive for this problem) at 3.00 mph relative to the earth. you observe a young girl jogging to towards you at 4.00 mph relative to you. the wind is blowing to the east at 20.0 mph relative to the earth. the park is also next to a marina. a boat in the marina is traveling to the west at 50.0 mph relative to the wind. the water is not moving relative to the earth. a hawk, traveling at 10.0 mph west relative to the girl, observes all this happening. by the way, did i mention you are also flying a kite, which is moving east at 7.0 mph relative to the boat. what is the velocity of the hawk relative to the kite? be sure to list your velocities with proper subscripts and signs on velocities (+ or imagine this as a one-dimensional problem like you did in homework. (report answer to nearest integer)
